I'm trying to prepare for a several day climb fest/group ride later in the year, which will include several long15% pitches in the mountains. In a typical 50 mile ride I'm trying to do at least 10 out of the saddle climbing intervals, from 1 to 5 minutes. It seems to use slightly different muscles than riding in the saddle and is just plain hard.
Comments from any of you Cat 1/2 guys and gals? I want to improve my ability to respond to sudden attacks on the climbs, and to handle the really steep portions of climbs.
