Cycling Time Trial Equivalent Calculator to McMillan Running?

Triathlon Forum
1

I often use the McMillan Running calculator to plug in a time from a recent race, to predict how I would do in a different distance race, given adequate training.
http://www.mcmillanrunning.com/mcmillanrunningcalculator.htm

eg, put in 22 for 5k and it tells me that I should be able to do 45:42 for 10k, 1:41:42 for a half marathon, 3:34 for a full marathon, etc.

Is there any equivalent online calculator for cycling time trials?

I just did a season’s best 15km ITT tonight so would like to see how this predicts my provincial 40k TT coming up mid-September.

Thx!

due to the nature of aerodynamic drag and the ever changing conditions, terrain at various outdoor TTs, it’s not possible.

however, if you use a power meter you can do some Coggan math to figure your mean maximal power curve for 15, 30, 1 hour, etc. and extrapolate from there.

If you have a good estimate for your drag values and atmospheric conditions, you can get some ideas with this calculator:

Why don’t you ride a 40k TT to see how you would do in a 40k TT? It only takes around an hour, and its a great workout.

If that just sounds like crazy talk, you might be able to use this calculator to get an estimate, http://www.triathloncalculator.com/

It’s easier to do for running, because air drag is not much of a factor for running. At least for runs of 1 mile to ultra-marathon distances. Not the same deal on the bike. Back in the early 1980’s a sports science magazine had a nice math formula for running. Maybe I can still find the reference.

My understanding is one hour power is .95 of 20 minute power, more or less, so you could ballpark it from a 10 mi or 20K event, assuming everything else is equal.

Hey you…
Dodging tornadoes last night, eh?

Did they change the course for Provincials? Last year it was 37K, not 40, running from Plattsville to Hickson. It’s close, why not head out and ride it, then try to adjust your time based on the fact it’s a race not a training ride (I’d subtract a minute). The course is flat but some of it isn’t as smooth as advertised.

See you out there

Cassie- My coach has developed a pace calculator/predictor based on on 2 times, i.e 1/2 mile time and mile time. This works for cycling, swimming and running. Semnd me a PM and I will send you my coaches info.

Hi SF, the tornados were moving NE and the course was out in the SW of the city, so we lucked out and it was sunny by the time the race started. Too bad you missed it. Low head/cross wind out and nice tail/cross back and lots of PBs all around. I took 1min16 off my 15km PB so I was very happy!!!

Nope, no change for the Provincials. I heard they were trying to get permission to block an intersection to make it the full 40km, but that it will probably still be 37km. I just said 40km in my initial post for the sake of simplicity. Yes, I do think I will try to ride it prior to race day.

See you!

Our club 40ks are done for the season, until provincials mid-Sept. I was just curious. When I’m in a running season, I use McMillan obsessively :slight_smile:

 Ok, thx, that makes sense.  Thx for the feedback.
