I haven't sprinted in a while. I found it mentally challenging to work on balance, explosive hip extension, fast cadence, and breathing all at once. Next time sprints show up in the workout I'll warm up with some Pose running drills. I learned about the Pose method at a CrossFit Endurance Certification in 2007 - it's helped me run my last few triathlons faster and with much less joint pain. Check out the CrossFit Endurance website for videos of their drills.
Power Clean 5 sets of 3 reps
10x 40m Sprints, Rest as needed
I rested one minute between each sprint. Tried to remember my pose form. Tried to start explosively. Balancing the forward lean with the hip drive at the start was the most challenging.
