We've been doing groups rides for weeks. There were six different group rides of 10-40 people just that I saw on Strava on Saturday. Nearly everyone's done with halting their lives for covid around here. The die is cast.
Anyway, I push up the hill a bit harder, as do most. Some too hard, but better than too soft I guess.
But If I were going to do a steady state ride, I wouldn't plan on doing it with a group. Group rides for me are only for going really hard. It's impossible to pedal consistently in a group, so I'd much rather do anything steady (endurance, sweetspot, etc) on my own so I'm not wasting 45 minutes coasting or in Z1.
