My reaching 50 miles on my Sunday long rides seems to be a will o' the wisp. Today I stopped early because a check of my Camel-Bak (at mile 44) showed that I was running too low on water. I wasn't sure that electrolyte drink would do if I ran out of water; it was about 10:30 am and getting very hot; there was no shade where I was riding; and the sun was blazing away.
So today I got in 45.6 miles. I tried to hold back the pace, but spent a lot of time doing low-gear, high-cadence riding (avg. 89 rpm; max 123 rpm). In its own way, that's as tiring as high-gear, low-cadence riding. But according to all I've read, it's better at burning fat, whereas high-gear, low-cadence riding drains your glycogen stores.
As usual, I got "fed up" with eating. I've told my gut to get moving, but it evidently needs more training! At least this time it didn't happen as soon as it did during earlier rides.
I was looking at an account of today's stage of the Tour de France. Whoever was in charge of the weather was thinking of that old song, "Hail, hail, the gang's all here..."
