Last year did solo 91 miles on flat roads with 800+ feet of ‘climbing’ 
and only 12.5 minutes downtime from 2 stops:
- 5:30:08 elapsed and 5:17:43 moving
- 12.5 minutes stopped for two toilet breaks and only one had water refill
- 3000+ calories burned on that zone2 ride that finished at 0.7 IF
- goal is to consume 50% of calories burned but only consumed 1000 calories from a banana (100 cals), 4 Nature Valley Oats ‘n Honey granola bars (400 cals), and 2 Roctane bottles (500 cals)
- 1 bottle with Gu Roctane, 2 bottles water only
Wished I had re-routed for water at the second stop. Starting temp was 70F / 21C and ending temp 90F / 32C. That was really a 9 bottle ride and I did it with 6 bottles - performance suffered the last 30 minutes!
