So on Saturday I rode 50 miles. Never had a problem with distances before. The wind was blowing at 25 - 35mph, which sucked on big climbs.

Now, while going up a 14.4% climb, I noticed that my right knee started to hurt quite a bit. It initially felt like a cramp, but a cramp that I've never felt before.

The pain is on the right side, sort of behind the back of my leg (knee). It doesn't hurt when I bring my ankle towards my glute (arse), but when I extend my leg out (as though I was pushing down on the pedal) it hurts quite a bit. On Saturday it sucked to walk up or down any type of incline/decline. Today, it doesn't seem to hurt quite as bad.

Just curious if anyone else has experienced this?

Now, to give a bit of information. This is my first 50 miler of the year. I am thinking that this can be potentially too much too soon. The most I've rode this year is 30 miles. I haven't changed anything out on the bike or adjusted anything.

Suggestions?
