Hot one. Pretty significant cramping last 10mi. Flatted at 19 mi. 4 different cars stopped to check on me, which was nice b/c my CO2 device randomly released leaving me with ~10 psi. A guy went to his house and brought back a pump and cold H2O.
Trying out DZ Nutz chamois cream and Hammer Fuels Perpetuem. Successful on both fronts. I like that the Perpetuem is neither sweet nor acidic, which is more suited to longer events.
