Tomorrow I will join about 15 - 20 other riders for a 115 mi ride around Lake Okeechobee. It will be my longest ride since I have embarked on this low carb diet.
The weather is "iffy" at best. 50 - 60% chance of rain, 80+ deg, high humidity. We'll be on the levee for much of the ride, so limited access to any "SAG." Pace is 20 - 22, with 3 planned rests: 45 mi, 65 mi (lunch), and 95 mi.
I did this about a year or so ago. Not particularly difficult as it is mostly flat, except for a few bridges and mounting the levee. Staying hydrated and keeping the 'lytes up to snuff will be key.
We'll see if the LCHF concept works for endurance rides.
