Since I've been primal, I have completed two 5k Obstacle Runs (Warrior Dash-55min and Champions MudBash-39min). I did not really train for either. I signed up for another in October (Iron Mudder), and I want to train for it, but I don't like the chronic cardio approach. Do you think since it's a relatively short distance I could successfully train for it following the primal blueprint approach (walk, sprint, and lift) or is some longer-distance running important?
Also, anyone think these races are anti-primal because of the distance? (Even if they are, I will continue to do them periodically because they are fun--but I'm curious.) I would like my exercise lifestyle to be as primal as possible, while still getting me to a point where I can complete one of these in 25-28 minutes. (This would be a hell of a feat for me, since the best time I have ever had for an individual mile was when I was in high school--around 8:45.)
