Isn't there a certain side effect with Fig Rolls?
What, Speed? (to the toilet )
Keeping my heart rate below 80% of my max i've done 50 miles with no food. Thats with a avg pace of 14.7 mph i did'nt try for 50, just a 3 hour ish ride at that HR, Atfer i got back i was feeling fine and could have done more. So as some have said keep your heart rate low and you will ride for hours without food.
