I did the downhill segment again, but this time around I purposely drafted a Prius, pedaled up to speed and went super aero tuck. Unfortunately the Prius was going a bit too slow and I wasn't able to get adequate room to slingshot me out of the draft forcing me to slow down. Even so I cut 4 seconds off my previous PR, while 4 mph slower with a top speed of 36mph. I'm beginning to wonder if the leaderboard riders were doing something similar or using their riding buddies to gain speed?
Honestly I'm finding this whole effort to go faster on this mini segment to be a great learning experience in technique and riding strategy.
