I tried my first deliberate fasted ride Wednesday. 12-14 hours after previous meal. Cup of coffee, nothing else. Usually I'd expect to bonk but it went fine.

Rode 30 miles below my threshold, felt comfortable but slow. Actually averaged 15.4 mph, only a little slower than my usual 16-17 mph on that same route. And the weather was tougher than usual -- our first really warm day, nearly 90 and muggy, with 22 mph whipping wind. The wind helped with tailwind on two short steep downhills and one long gradual climb, but otherwise wasn't much of a factor since it was from the side and often shielded by terrain or trees.

I'm not sure it was completely within parameters for fasted. The coffee had about a tablespoon of whey protein powder, but it was cold, in the fridge and ready to go so I drank it. And my water bottles had powdered electrolytes -- I didn't realize until I read the labels they contain maltodextrin, although in a tiny amount and the makers claim 5 calories and 2 grams carbs. Probably not enough to matter.

I carried a couple of gels but didn't need them. It was a surprise to discover I didn't bonk. In the past that's been a problem, although unpredictable. I suspect it had to do with inadequate rest. Before Wednesday's ride I got plenty of sleep and waited until afternoon. I'd planned to ride that morning after fasting only 8 hours and skipping breakfast, but felt so achy I took some ibuprofen and waited (I always get aching joints before t-storm fronts move in as the barometric pressure drops). So I went longer without eating than I'd planned, but actually felt better and more rested.

I'll try this again, maybe once a week or so. I'm curious to see whether it'll pare down those last few pounds of fat around my midsection. Might as well give it a try now since this is the closest I've been to my optimal weight and fitness in 40 years.
