I'm training for an endurance challenge and did my first 100 mile ride yesterday. This new stuff to me so I was trying to note how energy input and output was working for me. I ate very well before heading out (both the night before and in the morning) and at intervals where I felt hungry in the first half of the ride.
Three quarters of the way through I could feel some kind of energy depletion but not hunger. It's hard to say what it was - I had hit some hills after a lot of flat riding and felt bouyed by the more dynamic and challenging riding.
I took a few ten minute rests to eat but was in the saddle for 11 hours. I'm looking at 18 - 22 when I do my big challenge that I'm training for. I ate a fair amount of food - a tub of pasta I had prepared, 2x pitta with peanut butter, a couple of cereal bars, about 300g of nuts and raisins and a flapjack (a possible mistake - way more sugar than I'm used to).
I ate a fair amount when I got home last night too. Didn't go to bed hungry.
So I'm interested to know what other folk do for long rides. Also I'm wondering about recovery. I feel a bit tired today and will no doubt feel a bit creaky when I have to get on the bike later but I wasn't wracked with aches and pains. I might have been worried about my back (had a larger than should have been rucksack on) and didn't do any post ride stretches but it seems fine today.
