Sand bag carries are suck fests at those distances. Incredible strength endurance factor. My obliques were torn up by doing a lot of sand bag carries over the summer at the local junior high track. Good fun.
Coach Rut's is a BW sand bag carry, one mile, I think in 15 minutes... there was a thread around here a while back about it I think.
And 2 miles, even with a "light" bag at 50 lbs. is sadistic.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
