Today I went on a ride and noticed a tense sensation in my thigh. The outer muscle right above the knee. I am not sure why but I was feeling really good and ended up doing over 100 miles. On my way back home with 30 or so miles left to go; that muscle started to hurt really bad. Towards the end of my ride I could barely even pedal. The pain was so intense I almost had to walk home.

Anyone experience this pain before?

I was planning on doing a recovery ride tomorrow but I can't see this muscle feeling any better by then.

Any help would be appreciated.

Thanks
