notes:
*work hard on the in-gym work before settling into a pace you believe to be sustainable for all runs
*note which in-gym movements affect the runs the most
*60′ = 30′ over & back
*sled drag is not HYROX-style, you’ll be moving w/the sled while holding the black straps any way
*654m = 2 x 4th pole & back
*if still building in run volume/pacing or you anticipate having less than 2:00 of rest between intervals you can sub 2 x 3rd pole & back for 542m
