Hey folks, just poppin' in from the ss/fixed forums to ask a quickie. There is a path from my house that's approx 35 miles. I love to ride it. Lately, I've been thinking that I would like to double it up and do 70 miles some morning. Do I need to plan out when I do this? Do I need to pack a bag full of all kinds of stuff to eat, or will I be ok with just my usual water? I know that having food, planning ahead and whatnot will make it easier, but I'm less worried about ease than I am potential harm. Can I get away with a 70 mile ride without preperation? What about 105 miles, if I decided that 70 didn't fill the bill? This will be done on a fixed gear, if that is going to make any difference.
