I think that’ll be a story for many. It’s a question of how much you can gain from group as to how much you’ll tire if you go too hard.
Personally i think a good tow will gain you 30-40s on the lead in…. Will a rider lose that through being too high in the red, i’d say yes, and more. For me, i’d play it at sitting at below FTP by about 15% on the run in, maybe even 20%. Then around FTP up the hill… quick recovery and then pinning it down the back. But the back will be s much about who’s with you as much as anything. 2 riders or 3 pushing on down the hill i think could make up a minute on a solo easy, maybe even 2 mins by the finish.
I’m trying to think of a way i can do it so i can see both my power/riding as well as watching others. Maybe i should join as my lad via the iPad so i can scroll through people in crowd view etc… would be fun, but if i’m payin too much attention to them i’ll forget to pedal myself.
