Does anyone at the Uni do this?
I've been swimming 1km every day and running 3.5 miles every night (break at weekends) since October, and I'm not really feeling that much more capable on the CV side of fitness (I have lost 2 stone though, which is f'ing epic). Fartlek was recommended to me by a serving Royal Marine who swears by it. Is it much more different than interval training, and could it aid my CV more than my current regime?
