If you had to pedal..
I'm thinking worst case, you're on the road, in the middle of nowhere- buzzards circling around you in the sky and it happens.. you run out of oil mixed with gas.. what we all need to keep these babies movin'.
Without any downhills in site how long could you pedal for? I'm mean your adrenaline is pumping, maybe your on meth.. how long could you go for? How long could you last?
