im gonna be joining the marines and before i can go to boot camp i have to be able to run 3 miles in 26 min. the recruiter said to work on doing 1.5 miles in 13. so when i was running tonight i couldent run far. i felt like the coldness was sucking the oxygen right out of me. i guess my question is since it cold here in the notheast, should i sit outside for a little while for my body to get used to the temp? the local gym doest have a track and i hate running on the treadmills so my options are out side or travel to the other gym that has a track
