| | Halfbakery: Long-distance Swimming |
 | | Long-distance swimming is like backpacking, but instead of walking, you swim, and instead of carrying a backpack, you have a waterproof floating bag that you push in front of you. |
 | | I swim competitively, and after doing a 1500m long course in roughly 20 minutes, half the muscles in my body were cramping up. |
 | | Pushing a 35-pound floating pack would not limit your mobility too much because (a) youd be swimming mostly in a straight line, and (b) you could rest your arms on it allowing you to kick more efficiently with your fins. |
