Live Stream of my Danish Hour Record Attempt Tomorrow (January 11th)
Quote | Reply
If you're into watching people self-inflict pain, feel free to watch the live stream of me going for the Danish hour record tomorrow, Thursday January 11th at 5:30pm local time, which should be 11:30am EST. The current Danish record is 52.311 km set by Mikkel Bjerg.

There's an FB page about my attempt where there should come a link to the live stream: facebook.com/Tofthour. The stream should also come at feltet.dk. The commentary will be Danish, but hopefully they will show some split times or the like so non-Danes can still follow a bit.

It's going to be a bit of high pressure at 1023mb according to the current forecast, which is a bit annoying after several weeks of less than 1000mb, but it could be worse - Friday it will be more than 1030mb. They are working on heating the track as I write this...

I'll try to answer questions here, but am probably somewhat occupied on focussing on the attempt :)

Hi Martin, good luck for your attempt! May i ask you to share some photos of your bike setup if you dont mind? Will you be using the argon again?

If you can answer some pre race questions:

  1. Target lap time
  2. Target RPM
  3. What gearing
  4. How do you gauge your speed.....do you have a metronome virtually locked into your brain where you "listen" to the beat like a musician
  5. Implicit in question 2 and 3 is your target speed, but help us with that calculation
  6. What heart rate do you expect to hold at the target gearing and RPM
  7. Is this attempt at sea level
  8. What is the surface of the track
  9. What is the velodrome temperature and barometric pressure?

I won't bother asking questions about equipment etc. I figure those thing will be obvious once we "see" what is going on. My questions above are items we can't just see on the stream but relevent to the human performance.

Best of luck. Love the hour record attempts. Even cooler to have an STer going at it at the elite level.

Thanks!

I will be using the Argon 18 again, this time in small, though (allows me a bit more flexibility in terms of position changes, though the current setup doesn't need the lower stack). It's largely the same bike setup with the biggest change probably being the use of my aero road SRM crank set, which then means I use a 58/14T gearing and road chain instead of 54/13T gearing and track chain. There's also a helmet change, but you'll have to see the live stream to see what that is ;)

Thanks, Dev.

1. Target lap time

Whatever beats 52.3 km I guess :p I believe that's around 17.15 sec.

2. Target RPM
3. What gearing


58/14. That should result in something like 101-102 rpm at 52.5 kph.

4, How do you gauge your speed.....do you have a metronome virtually locked into your brain where you "listen" to the beat like a musician

I will get current lap time and average speed so far displayed on a screen at the track side.

5. Implicit in question 2 and 3 is your target speed, but help us with that calculation

I will most likely start out targeting 52.5 kph and then adjust from there once I'm perhaps 20-30 min. in. 52.5 kph should be possible even with the somewhat high pressure, but with a bit of luck I will be able to go 53 kph. But the focus is on beating the Danish record so I won't start out targetting 53 kph - if it was low pressure I might have. With a bit of luck I will do ~2100 W/m2.

6. What heart rate do you expect to hold at the target gearing and RPM

I use HR as output, not input. I will probably end up at something like 175-178 bpm average.

7. Is this attempt at sea level

Yes. It's in Ballerup Super Arena (outside Copenhagen, Denmark), 35 metres or so above sea level I believe.

8. What is the surface of the track

Wood. Apparently not the fastest wood out there, though.

9. What is the velodrome temperature and barometric pressure?

I have asked for 27C, but they haven't promised anything. Sea level pressure looks like it will be 1023mb in which case it should be ~1020mb on the track.

I became a fan of this event when Moser did 51.151km back in ~1985 at Mexico City on concrete....thus my questions about surface, altitude, barometric pressure and temperature. Best of luck.

Looking at the synoptic chart, It looks stormy, so at least there’ll be a little bit more natural humidity. The pressure will be 1022-1023hPa (1018-1019 at the stadium) and fairly steady by then, as you say.

All the best.

Good luck to you on your quest. I feel that you will do very well.
I will try to watch at least some of your effort.
Every since Jensie tried the hour, the event has gotten new attention. A bunch of us at work were so focused on that effort that not much got done. I won't have that liberty tomorrow, but wish you the best.

indeed, and in the pictures from his last attempt a while back he also had a really low head position like that.
That's really tough to do on the track and still hold a good line. Impressive.

I would say hands down world record for a “hobbyist†who actually has a job.

Lost of respect for this effort, especially considering all of the behind the scenes technical work he has to do to get it right.

Well done, shame the pressure wasn’t in his favour to get him to 53. Looking forward to the report.

Thanks guys!

A few short notes before hitting the sack. Official distance 52.324 km - they first reported a lap too much for some reason, which also seemed off compared to my timing guy on the side line.

From a brief look at my power it seems like something was a bit off, my CdA has consistently been lower in training as well as in last year's attempt than it was tonight. Zero offset of SRM was only moving a few points before vs. after, so power should be right. Should have gotten ~500m more had I just had the same CdA from last year (and if anything it should be slightly better now). Will have to see if I can find the culprit - hopefully that will be easier to nail down than adding the power I have added compared to last year.

Oh, they didn't really succeed completely in heating the track, conditions on the track were 24C, 1019 mbar, 36% RH.

Just around 5 W/kg - had a bit of drop-outs in the file, but it's right around that.

Thanks for sharing. Your CdA is amazing, even with you mentioning something was off. Very cool to be in the record books, putting out that power, in a very difficult position, on the track.

Those base bars also look like they are way wider than 3:1. I thought UCI had rolled that back for frames but kept it for bars or am I totally clueless.

pretty sure those are the stock pursuit bars on the Argon (I think Norm Alvis' were the same at least) so they must have met UCI approval.

I saw Norm's setup and thought WTF. Master's rule enforcement is all over the map. I have done road nationals and one year they show up with jigs and enforce saddle angle (less +/- 3 degree tilt) and total length, but not saddle/bar height. The next year they just weighed TT bikes, so anything goes. The year after it is total BB to extension length. Then I know last year they gave some people the 3rd degree for stupid things, like not enough water in the P4 bottle, but do whatever the hell you want with a P5. No measurements whatsoever at TTT nationals.

At some point I think they realize that old folks have enough health issues that aesthetic issues like saddle angle aren't worth enforcing (nobody cares what your bike looks like because you are lucky if your wife and kids even bother to show up). It would be nice if they would at least settle on a set of rules that were "reasonable" and stuck to those. Maybe the Brits and their CTT standards are onto something.

The ctt have their own set of unenforceable rules.
We have Graeme Obree to blame. His genius in pushing the limits during the 90s along with the UCI not liking him then rushing through some arbitrary rules that have been updated and played with have left us with the rules we have now.
In a way triathlon bike rules are nice and simple and allow for more innovation.
I digress.
Mtm did a great ride. Very intelligent too.

He also took out one of Boardman's earlier times!!! This is what I get for not checking into ST and getting carried away at work. Is there a replay of this anywhere on the web???

Super congrats. What would you think that the ideal barometric pressure and relative humidity needs to be for the most favourable attempt.

When you are at sea level you want the pressure as low as possible, and humid air has a lower viscosity than dry. Regarding the pressure, the highest fast tracks are in the 6-7k ft range, although higher would probably gain some speed for most riders. I don't know if a study has been done to determine if the viscosity lowering of humid air vs loss of oxygen content is a net gain, or if there is an optimum humidity.

Hehe. I think I found the problem. I think the culprit was simply me forgetting to turn off auto-zero on the SRM - IMO they should get rid of that feature or at least make it off as standard as (IMO) anyone that doesn't know how to manually zero their powermeter is probably going to be at least as well of with something cheaper than an SRM. In training I used the Edge 1000 between my arms, but for the race you can't have a computer that you can look at, so I used my Ege 520 under the saddle for data collection. When you connect the SRM to a new computer the auto zero feature is on by default and I simply forgot to turn it off. Hate that "feature" on the SRM...

It's the standard integrated stock pursuit bar from the Argon 18 Electron Pro track frame set. They were used by the Danish pursuit team in the Olympics in Rio (where they got bronze medal) and are actually quite thick, so I'm pretty sure they're within UCI regulations.

Will have to see if I can find the culprit - hopefully that will be easier to nail down than adding the power I have added compared to last year.

Oh, they didn't really succeed completely in heating the track, conditions on the track were 24C, 1019 mbar, 36% RH.


Super congrats. What would you think that the ideal barometric pressure and relative humidity needs to be for the most favourable attempt.

Pretty much as low barometric pressure as possible. A lot of my training days I had between 980 and 990 mbar, which should give around 700 metres or so more in total distance compared to 1019 mbar. Humidity should also be higher, but has less of an effect and you probably don't want it all the way at 100% RH, but something like 70% would probably be fine - maybe depending a little on temperature, but if temperature is only 24C then I don't think 70-80% RH will be any issue.

Just did a quick calculation. If it was 980 mbar, 27C, and 75% I would have done almost exactly 1000m more (for the same power and CdA) - and that's actually without counting the slight decrease in Crr that should accompany a higher temperature.

So you got it by 13 meters? That's less than a second. Crazy awesome regardless of the record.

It's 'funny', but by my calculation I actually get 52.335 km, so 24m more from the official times I've seen. I'll try and hear if they have some explanation from the discrepancy of their calculation vs. mine. But 24 m is of course still not much, though I thought I had it decently under control. I was closely following the average speed from my time keeper (which ended up at 52.34 kph according to him) and saw I crossed the needed 52.311 kph with around 2.5 minutes left. From then on I just focued on keeping the lap times under 17 seconds (52.9+ kph) to know I was beating the record and the last time I looked at the average speed it was at 52.32 kph with probably somewhere between a minute and two to go.

If anyone wants to calculate the distance at home, this is the times I've gotten:

209 laps in 59:54.227 minutes.
209th lap done in 16.892 seconds.
210th lap done in 16.820 seconds.

I believe you use the pace from the last complete lap (i.e. the 209th lap) to calculate the distance covered on the last (incomplete) lap (a little counter-intuitive).

Hello Martin and All,

Could you comment on how your arrived at your helmet choice?

And did you need to modify the helmet?

Testing ;) The helmet tested faster both times I tested it when I lowered my head and looked a bit down like I actually prefer to do on the straights. I think it might effectively gain me more outside as I can ride in that position more of the time (no bankings all the time).

No modifications on the helmet - it isn't allowed, but I don't think they're that strict about it, though (as long as you don't go crazy).

I also got 52.335439 hand calculating it out so exactly the same thing you got. I have always wondered how they calculate out those last meters. Makes sense it is the penultimate lap.

Even if you use your avg from the first 209 laps you get 52.3339.

Hello Martin and All,

Thanks ...

Do you have still a pic of you on your bike to observe your position?

In the video you are moving fast and the focus is of the whole arena .... so difficult to see your setup.

There is a still picture on this thread but would like to see more of your setup and position.

Also what is different in your setup for a non track TT? ... (bike obviously) but other items ... it sounds like you use the same helmet?

Cheers, Neal

I have only seen a couple of pictures from the race itself, all on the banking like this one:
https://jyllands-posten.dk/...ee/ok-timerekord.jpg

Edit: You can get a bigger version of the picture by clicking on it in the article:
https://jyllands-posten.dk/...ny-dansk-timerekord/

The position, skin suit, and helmet is all the same as on the road, only the bike is different. Well, the hand position is slightly different since the extensions are placed so far apart on this pursuit bar so have to be angled inwards a lot, but that is one of the things I hope to get changed if going for the WR.


Found an image from the front on the straights:

Hello MTM and All,

It looks like a POC Tempor helmet .... are using the visor .. or glasses?

If so ..... did you tape over the front vents for the record or does that make it too hot?

Cheers, Neal

Yes, POC tempor with the clear visor. Didn't tape over the holes - haven't tested it as it's strictly not allowed and I'm actually not sure it's faster with the air channeling POC seems to have incorporated into the helmet. I guess it should be tested - if it proves faster I could try and hear if POC could make a helmet without the vents for me or maybe just fashion some official plugs to use (like the LG P-09).

ETA: Could be interesting to try some of your glasses to see if I could hold my head low for the optimal position for more of the time. Not sure what the UCI would think, but I don't think it's prohibited (but the commissaires could still give it a no-go if they felt like it I think).

Do you have vents in that helmet? If so, is it actually improving the aeroness of the helmet with pass through airflow generating less drag or is it for cooling? Or maybe there are no vents and I am just seeing two black dots!!!!

Hello MTM and All,

Congratulations!! ................. Chapeau!!

I was asking because I have a POC Tempor in the box that I have not used .... I bought it some time ago based on reports of it being very fast ...... but also very sensitive to head position .... and never go around to giving it a go.

I think I am going to give it a try now.

Thanks for the pics:



With your record perhaps POC Tempor sales will see an uptick. .... also with the new 'Star Wars' movie they are back in vogue.

I would guess that the View-Speed glasses .... as sort of advanced technology ..... are not in the spirit of the new rules for the 1 hour record ....

and might not fit well in the POC with its small visor.

It appears that the rules are trying to maintain the spirit of ...... 'not about the bike or technology'.

http://www.triathlete.com/...or-aero-helmet_71122

and

https://www.competitivecyclist.com/...empor-raceday-helmet

http://www.bikeradar.com/...poc-tempor-14-48752/

Excerpt:

"On the road you can actually feel that happen too – when you have your head low enough, it goes quiet and your speed lifts. We did a personal best on a local TT course in it, too. [emphasis added]

So it's a winner, right? Wrong. You need to have your head extremely low for it to perform at its best, it gets buffeted when you turn or drop your head, its unstable over bumps and, incredibly, above 45mph it lifts and floats around. That’s as disconcerting as it sounds."

I figure I can hold my head in the optimum POC position ... but I will have to give it some practice time .... and I can fix those other minor complaints.

Cheers, Neal

I actually think they might have discontinued the Tempor since it doesn't seem to be on POC's site anymore, but I'm not sure.

Yes, UCI might very well not like the glasses for the hour record. I was also thinking about them for the road, though, where they would probably have less objections. One could always test without the visor if it interferes with the glasses. The visor might not make much of a difference, especially with the low-head position.

Now that it is over, I would like to ask some questions about the mental aspects of the event:

  1. Taking out the physical part (I realize that this is not easy), but was it harder to mentally focus to not overcook the pace early (Rohan Denis overcooked it relative to you), or was it harder to keep the pace up in the end. This question is hard to decouple since there is the additional layer of pain management to deal with in the latter
  2. Which part of the face was hardest...I assuming 30-50 minutes because now you have the pain buildup from the first half hour, but you have a long way to go.
  3. Were you counting RPM in your head or just looking for lap times track side during 2.
  4. How many breaths per minute were you taking? 100, 150, more? Or is there no sychonization between your pedaling rate and breathing rate.
  5. How much "extra" distance do hour record athletes on average tend to ride due to non optimal trajectory through the turns and where you doing things to focus to take the shortest line. If you can save a meter or half a meter per lap this quickly adds up?

Normal respiratory rate during submaximal exercise is typically only 25-30 breaths/min...most people don't get up to even 50 breaths/min even during exercise at VO2max.

There is some evidence for entrainment (the technical term for synchronization) of respiration and pedaling during cycling, but it's rather weak, probably because cycling (in an upright posture, as used in lab studies) is an almost optimal modality for unconstrained respiration.

IOW, don't overthink it, just breathe (and pedal, of course).

52.335 from me too. Your before and after whole lap averages were 52.334 and 52.339 - the two averaging methods give 52.335 and 52.336 Personally I would prefer the interpolated method than extrapolating the penultimate lap but the differences are small. One advantage of the latter is that once the hour is up, what happens is irrelevant so there can be no issue of crossing the line at 59:59.9 vs 1:00:00.1

PS Well Done

1. It's two pretty different things that I don't think you can compare directly. It's almost like asking what is most comfortable, too hot or too cold. But it's not 'hard' per se not to start out too fast, it's mostly about making due diligence about your capabilities before you start.

2. I think the hardest part was keeping the pace up between 25-45 minutes. Before that it's pretty easy when you have a good idea about what you can do, after that you can see the end and pace by feel.

3. I just looked at lap times and average speed until now. I felt comfortable I could beat the record if my average speed was at least 52.2 kph with 10 minutes to go.

4. No idea, I normally just breath. Once in a while I might focus on breathing, but it's mostly to keep my mind on something else than whatever is hurting.

5. I don't know exactly, but I don't think it's more than a few hundred metres at most unless you're very inexperienced from the numbers I've seen and my general impression when looking at distance data using a wheel sensor.

Just saw this. Great job! Amazing effort. I can't imagine the pain and scary places the mind may go during that hour.

I try to follow all the Danish cycling stuff since I work for a Danish company that sponsors a pro team. This came up in a search of recent events.

Hi Martin

Congratulations. It's exciting to follow your quest for the world record.

A helmtet question again. Was the Poc Cerebel ever into consideration as a choice since you chose to change between two head positions on the straights and in the curves (and why/why not)?

Thank you :)

Yes, I have also tested the Cerebel. The Tempor is faster in the low head position, but it's not possible to keep that position in the curves as you have to see where you're going to hold a good line. But it's still faster over-all with the head down lower only on the straights.

Novo. They sponsor all the Team Novo Nordisk riders and athletes. People with type 1 diabetes doing things I could never do.

Most people avoid team kit like plague if not on the team, but as an employee I believe in those athletes and feel wearing the kit around town brings conversations to spread the word I never would have had otherwise.

Great Job!! Can I ask about your training for hydration and food intake? I don't see anything in the picture and doubt you are taking your hands off the bars for a drink. What was your training for adaptation to be at near max for a solid hour without food or water? I generally don't eat unless longer than 2 hour ride, and don't even bring a bottle if I am out for less than an hour, but I am not working at the level you were. Thanks.

Cool, I know that team - they're always part of Tour of Denmark. It would be nice if they would make a Danish team of that caliber (there are no Danish teams on the WorldTour or even Pro Continental ones), but I guess that wouldn't make as much business sense.

Thanks!

As far as I know it's not allowed in any track races to have any fluid on the bike and I don't think you are allowed to carry any food either, at least not for the hour record. I remember reading about the Danish hour record and it said something along the lines of it being permitted to get handed water and fruit during the attempt! Shows you how old those paragraphs are. But anyway, I didn't train specifically for not having food or water for an hour - it's not really an issue if you make sure you have been drinking and eating well leading up to the attempt. If so, glycogen stores should last you up to a couple of hours of intense excersise so no issue there and with regards to water it has to be quite hot for you to sweat more than the ~2% body weight that you can sweat before it starts to hamper your performance. It's been years since I've used any food or fluid in a TT - the 40k worlds TT in ~35C and full-on Sun in Qatar in 2016 was borderline in that regard, but it went OK without.
