Long time singlespeed endurance racer here and by far my weakest skill is riding long gravel climbs. I can shred the descents and power up all the steep singletrack climbs but the rest of the field walks away from me on long steady climbs. I have to stand where they can sit and spin. I live in a very flat area so I don’t have access to anything remotely close to the things I encounter at the races but was wondering if there’s anything I can be doing to help. I’ve made the podium at a few 100’s and other endurance races but I lose so much dang time on the gravel. Help!
