this is only my second season riding.. here is my issue.. i go to the gym a few times a week, do mixed martial arts as well, run 2 to 3 miles a week.. in generally good shape or at least i think so.. 6 foot 3 roughly 200lbs...
when i ride.. first few hours of riding no problem feel great.. but after that this ONE area in my legs just really start to burn out fast.. muscle group above knee in the front of my leg thigh area.. it just sucks.. because im just learning how to ride and LOVE it.. but this pain really cuts down on my ride time.. the next day its still a little sore.. within a couple days its back to normal..
am i doing something wrong? bindings setup wrong? or am i just a bitch

.. what can i do to remedy this... i LOVE to ride but need to make that NOT hurt..
any help/advice would be greatly appreciated..
