So I did my first metric century this past weekend with a local bike group. Up until then, the longest I've ever gone is 50-55 miles and certainly not as much climbing, maybe 3000 feet. The metric century had just under 6,000 feet of elevation gain - two major climbs. The first was about 1700 feet over 4.5 miles and the second involved 1900 feet in approx. 7.5 miles.
By the second climb, I was slowing down dramatically and started cramping in both legs - definitely in the quads (almost in the calves - you know that feeling when you the muscle starts to seize up, but then you relax the muscle enough to prevent it from fully seizing up.) The group pretty much dropped me by then but I had to keep going to get to the regroup. I could keep the pedals turning, but just barely - maybe 50-60 rpm - and that's in my granny 30x25. Going maybe 5 - 6 mph. Made it to the regroup, only to get dropped again in the next section. Able to recover a little on a downhill stretch, but had no power. A few minor bumps to get over the rest of the way home, but I just couldn't put any power into the hills - if I even tried to stand, I'd get that "just about to cramp" sensation.
Dinner the night before was rice, veggies, chicken. Breakfast included bowl of cereal, muffin, two bananas. I had a powerbar at 28 miles, packet of gu during the second climb, and a packet of jelly belly sport beans at the last regroup, approx. 42 miles into the ride. Two bottles of cytomax and refilled with water at the regroups.
Anyway, what's your diagnosis? Was this a bonk? Did I not eat enough during the ride? or do I just need to put more training time in?
