Hello everyone. I just participated in an incredible tough group race. The race consists of teams of up to 40 riders, riding a rolling paceline (Belgian tourniquet). The fastest team from start to goal (which is 210 kms) wins, and our goal was to make it in 5 hours max. This means 42 km/h. I manage to stay with the group and take my pulls for 3 hours and 40 minutes, and then I was basically spent.. I didn't bonk, my muscles just didn't want anymore. I had 280 watts on average when I had to let the group go (we had a headwind).
How do you train for such event? I don't want to lose the group next time.
