i do very well on long medium climbs where i can stay seated and spin fast and can hang with many of the faster guys in this area, and i can drop a majority of riders i encounter. for some reason though, they all kill me on shorter, steeper, out-of-the-saddle climbs. why is this? do i need to do some weights for the quads or what? what are the best training techniques to improve your climbing, both on and off the bike?
