That's exactly what I did. I'm suffering from a back injury that laid me up for over a year. I'm still in pain everyday but I just hop on my bike and try to not think about it. I peddle through the pain.

I say, just go for it BUT do it smart! Get a checkup from your doctor before going hog wild. Then load up on quality food, hydrate yourself and take it SLOOOOOW. Stop as often as you need to and easy on yourself.

If you want to attack the task a little bit more timidly, then drive part of the way, park, then ride your bike the rest of the way until you build up some stamina.

Good luck!

NOTE: I can't stress enough about having enough food to fuel you through your trip and being properly hydrated. I can't even pedal 2 feet without feeling like I'm going to pass out if I don't eat right and am properly hydrated. You have to fuel up on quality foods and have lots of water before, during and after your trip. Also bring along a filled water bottle, a Powerbar or another snack to nibble if you need it.
