More of a mental grind than anything. Be smart from the start with your pacing and make sure to still push the pace on those runs. Set yourself up for success with taking the time to lock your feet well on the rope climbs and make the most of the pull. Once you get to those burpees dig in. If it’s helpful try doing 5 quick reps and 10 more pace reps to break the monotony of the 100 reps. Remember that you can always do 1 more burpee so stick with it. If you need to back off to meet the goal time domain check out the scaled version.
