2x5, 5x1, math is hard...

2x5 min intervals w/2min recovery between intervals

Next interval scheme starts after the 2min recovery

5x1min Intervals w/30sec recovery between intervals

Hold maximal distance possible on each of the set intervals.

5 minute intervals, .75 miles both times

1 minute intervals, maybe 280 meters.

Running barefoot in the mud seems to knock off some speed!
