Here's an odd one:
I am helping deliver a 40 foot boat from the coast of France to the Caribbean this fall. The first leg will be about two weeks to the Canary Islands for a few day replenishment stop and then weeks three or so to the Caribbean. I expect to do pushups, situps and pullups, but that isn't going to do a lot for my cardio or legs.
All in all, I would expect to be spending about 6-7 weeks off the bike. I wonder if anyone else has a similar experience and can share what they did to keep fit in a small space.
