As it's the month of Ramadan, I'm fasting, which means no food or drink during daylight hours (approx 5am to 7:30pm). My daily commute is a 13-mile round trip with one or 2 minor hills but nothing excessive. Intuitively, I'd think it's probably dangerous healthwise to do this distance by bike without being able to re-hydrate? If I did try it (some might say don't even entertain the idea), what sort of food should I eat before the fast starts? I'm guessing porridge and the like... Cheers.
