ISO TT #2 - 24km Merckx-style ITT

Updated: Jul 29, 2021

Another brilliant day of ISOlated time trial racing today in Bangalore. ~55 riders turned out to take on the the 24.4km OMR TT segment vs. ~45 riders last time around. And we had 23 riders who showed up to both ISO TT's to measure the improvement they could make in the "most improved" rider ranking with 3 weeks of training in between events. After the gale force winds last time around, the less windier conditions today were welcome by everyone, and a couple riders made the most of it to set some fast times and make big improvements. Top work by everyone who showed up. Images (by Prasanth Sukumaran/PS Frames) and results are below.

Thanks to everyone who came out and made the most of the ISO TT series. I'm passing on the race organizer baton over for now. See you all out on the road.

Ride lots!




Aight, it's time to pull up those socks and go to the races again this Saturday, August 29th. Same time, same place, same bike setup, hopefully stronger legs! The weather looks gorgeous, with slightly weaker westerly winds, which means less of an assist out, but also less of a struggle back; a brilliant opportunity to better your time from last week [Iso TT#1 report and results], or set a good time if it's your first time out.

Event Brief

Date: Saturday, August 29th

Start window: 6-8AM (it gets windier as the sun wakes up, so earlier start = faster time)

Distance: 24.4km

Weather: ~22C, ~15kph Westerlies, 0mm precipitation [Dark Sky]

Race execution

  • No pre/spot registration, just self-start and execute as listed below

  • Start a new ride on your device once you're done warming-up, and you're ready to start.

  • The segment starts and finishes at the same point it does for all BAR/BBCh races, and I have laid down an orange Strava logo on the road

  • Read Addendum to Rules based on IsoTT#1 below to avoid issues that riders had last week w.r.t. NO-drafting enforcement/DQs, no-show on Segment leaderboard, and segment times discrepancies

  • It is important that you make the following two options on your Strava 'Privacy settings' to ‘Everyone can see' for (1) 'Activities' AND (2) 'Flyby'

  • Here's a how-to on opening Strava Privacy Settings to show up on the segment leaderboard:

Rules and regulations

  1. This is an Individual Time Trial, so NO drafting. This includes other racers on course that passed you, or you pass, or that auto that's flying past you. The event is an opportunity to see how fast you can go with the power in your legs, and improve on it the next time out, so don't let yourself down

  2. This is a Merckx-style ITT, so leave your fancy pants TT bikes, disc wheels, and road bike clip-ons at home, and bring out your road/fixed/MTB/hybrid bikes for this one. It's particularly busy on OMR as the country bustles back to life with trucks Shumacher-ing down the road and the south-westerly monsoon winds blowing across the OMR, both of which can have you splat on the highway which ain't worth the savings from your aero accouterments

  3. There will be a couple volunteers/neutral observers/photographers out on course to make sure everyone is keeping their nose clean, and it is encouraged that riders look out for each other and report any riders who are not riding in the spirit of the rules

Addendum to Rules based on IsoTT#1

  1. Correlation Score and Spatial Score on Strava Fly-Bys can be used to enforce anti-drafting. 2 riders with a CS or SS of above 75 is an indication of a drafting violation. Along with a corroborating rider testimony, the infringing riders are DQed

  2. To avoid unintentional high CS or SS scores, when teammates/friends start together, let the stronger rider start ahead, and if of equal strength, leave with significant insurmountable time gaps

  3. If a stronger rider catches and passes a weaker rider, the rider who has been caught must not follow behind in their slipstream. The rider who has been caught must drop back to at least 25m behind the rider now in front. There isn't wide enough berth to race 2-abreast on open roads without benefiting from a draft, and without putting other riders lives at risk

  4. If a rider is using a low fidelity GPS device, their elapsed time might show as higher than moving time/time-on-device. Regardless, a rider's Strava segment time is the final deciding time in any case

  5. Start your ride ~50-100m and ~5-10sec before the marked segment start and finish it similarly after the segment finish. This will allow your GPS time to lock on to and register the start/finish of your segment effort. Strava will do the magic of resolving your exact segment time. Feel free to use your lap button to get a second measure of segment lap time for your own personal record

  6. If a rider has not opened up their privacy settings (for the day at least) to be included in the segment leaderboard, they will not show up in the results

Ride lots,
