Sorta an after the fact observation but I hit what felt to be a bonk point about 5-6 miles after this picture; early in terms of time and mileage from my usual. Happily it was only a couple of miles from my house and on the way back through a shady area, so I didn't have to tough it out for any length of time. Good thing because I felt listless and like crap the rest of the day. I think I pushed my heat tolerance envelope pretty hard.
Yesterday was my 8th day in a row of riding, time to take a day off. I'm installing shelving in the house today. Heading for 100 again today (and tomorrow).
