At about 40 miles into a ride this morning, my quads started to hurt pretty badly, even when I wasn't pedaling. In fact, they hurt more when I wasn't pedaling. I pushed through another 10 miles and when I got home it took about 15-20 minutes for the pain to go away. The pain was constant whether I was moving or not. I've been mountain biking for 3 years and been on 5 hour rides and never felt anything like this. I've only been road riding for about a month. Is this a a function of not consuming enough calories? Electrolytes? Maybe dehydration?
I consumed about 150 calories of homemade gel 45 minutes in, another 150 calories about 30 minutes later, half a Clif Bar 30 minutes later and the remaining half 30 minutes after that. I finished in 3 hours. As I type this, it's becoming apparent that I didn't eat near enough, but is that the cause of the pain, or is there another possible cause? I only drank a bottle and a half of water, but it was in the 40s, so I wasn't exactly sweating much. Thanks for any input
