Are you varying your position? Could also be worth tweaking your saddle height.Anyone got any tips on avoiding painful thighs when cycling?
I just did a 40mile ride and in the last 10,despite it being easy going, the muscles down the front of my thighs felt like they were going to explode.
I’m used to doing 5-20 mile rides. Is it just the muscle burn as I work my legs more? I got off my bike feeling that my core fitness would allow me to do another 20 miles. My legs said otherwise!
