Wow; good for them. The hacks have gotten out of control. It used to be one offs were strictly forbidden, whereas now anything goes. The Wild West of aerodynamics needs some regulation.

Now get rid of lead mottos, and make any motto involved in the race pass a basic aerodynamics test. I would venture to guess that 99.9999% of all people, and probably 80% of ST, doesn’t realize that a motto behind a rider actually helps that rider go faster.
interesting but begs the question, on what basis will setups be approved or not? for that matter, what setups are considered fairings to require approval - any BTA could be considered to be a fairing, any non-round frame bottle, frame integrated hydration systems… many pros could have their whole aerobar system banned.
good on them for tackling what is increasingly becoming an insane arms race but the devil will be in the detail of where lines are drawn.

I am going out on a limb here, but I suspect Joe Skipper’s setup does not get the thumbs up.
Yep, skip dawg ruined it for all of us. He just went too far 🤣

Here here - moto’s have most influence on the fast swimmers so they get the advantages on the bike. I think Roth is one of the worst offenders as well. Lets hope its a fair race for everybody.

yet you can use prototype run shoes in roth this year .
What if you put a bit of water or some sports drink in a bottle down the jersey and pull it out to drink a few times - would that skirt the aero fairing rule? I could see some pros trying that approach.
Technically, it is not Roth that is banning them - they are not permitted under DTU (Deutsche Triathlon Union) rules. So this would/should apply to any races run under DTU rules.
And any fairing water bottle set ups need to be approved. Not sure if this also applies to AG’ers. Being reported on IG from TheTriathlonHour account.This was sent to all PRO athletes a month ago and all shared on 2 June by @jcbesse in @Jim’s bottle down the chest test (see other thread).
I think the usual issue is the rule is not very explicit in what constitutes a ‘functional piece’ like hydration system vs a ‘fairing’…
It clearly needs updating at some point, and until then it’s to the discretion of whoever is enforcing the rules.Agree. As you said:The german (DTU) rules say “Zusätzlich angebrachte Windabweiser und Verkleidungen am Körper des Wettkämpfers sind nicht erlaubt.” which roughly translate to “Additionally installed wind deflectors and fairings on the competitor’s body are not allowed.”. Roth has chosen to interpret it as (email sent to PRO athletes): ‘Any “Aero-Inserts†- for lack of a better word – you put into or attach to your race suite are not allowed.’ One could argue what constitutes an aero-insert vs a bottle or whatnot, but I think the intent is clear (and hope they push through with it)
IM Rule 5.01 (m) Except as set forth below in Section 5.02(b)*, additional equipment that has the effect of reducing wind resistance is prohibited during the bike segment of the Race (whether such equipment is worn under the athlete’s clothing, over the athlete’s clothing, or is otherwise attached to the athlete’s body or the athlete’s bike); (DSQ)
- 5.02(b) covers helmets
The way ahead here is deterrence, which will minimise the need for enforcement.
A clear message from race organisers to athletes describing how this rule will be policed/enforced would help, and then informed shouty referees on the route from bike racks to mount line delivering that enforcement (DSQ if not remediated immediately). The “bike segment of the Race” doesn’t start till the mount line: cross that with stuff down your front and it’s a DSQ.
Challenge Roth (presumably under DTU Rules) can show the lead here.
It’s enforceable for a pro field, but this could be hard to enforce on an amateur field. Camelbacks, loose jerseys, etc, but importantly the amateur field has a variety of body shapes that the pro field doesn’t. I’m sure no one would be upset about an overzealous official DQ’ing a larger rider for a ‘bottle’ that turns out to be a body part.

I’m sure no one would be upset about an overzealous official DQ’ing a larger rider for a ‘bottle’ that turns out to be a body part.I suggest that a referee who can’t tell a bottle down the front from ‘natural body structure’ when athletes are running their bikes from the rack towards the mount line need either glasses or ‘body shape training’.
But the possibility of its enforcement (plus peer pressure, let alone aesthetic displeasure) will act as the necessary deterrent to elite and amateurs alike.
Shoving a 500ml bottle down the front during the ride isn’t going to achieve the gainz so doesn’t need enforcing. That does not infringe the rule I posted ^^^ (becos not aero benefit*).
“equipment that has the effect of reducing wind resistance is prohibited . . .”

Now get rid of lead mottos, and make any motto involved in the race pass a basic aerodynamics test. I would venture to guess that 99.9999% of all people, and probably 80% of ST, doesn’t realize that a motto behind a rider actually helps that rider go faster.
Is it due to the buble of air the moto is pushing in front of it? If so, yea me, I am in 20% of ST and 0.00001% of all the people. Can wait for clarification…

Ever watch NASCAR on the super speedways or the Indy 500? Two cars are always faster than one.

Basically yes. A really great paper written about it. “This was later also confirmed by studies by Defraeye et al. (2014) and Barry et al. (2015). Blocken et al. (2013) related this effect to the so-called “subsonic upstream disturbanceâ€, i.e. the upsteam effect that every obstacle moving in still air has upstream of it. This effect is a direct result of the elliptical mathematical character of the governing partial differential equations for subsonic flow.”

What’s your motto? Nil desperandum!

It couldve been banned on the basis of making the bike media photos hideous alone
Banning the shirt fairing and stilt shoes will put the Kona record out of reach for a while. Maybe they need to reset the record like they did with the hour record.
next they will ban pacers on the bike and run?
