I've noticed over the last couple of months of training that my quads start to burn WAY before anything else, both in time and intensity. So much so that I think my FTP would be 20-30 watts higher if I had more endurance in this part of the body. The burn is in the top right portion of the quad a couple of inches up from the knee.
Is this a bike fit thing or a quad strength (endurance?) thing? If it is a strength thing, is there anything specific I can do? I've been putting in a lot of LT work and seeing great results, but unfortunately my quads never seem to have the same failing point as the rest of my legs (calves, hamstrings, etc).
