In less than 36 hours, based on the metrics used, I improved my running economy22 100% in
the first two phases (3p1.5, 6p3) and improved desirable air time 33%.
Over the full two days of the certi cation, we covered more than six hours of whiteboard
mechanics and hundreds of details. In practice, four things helped me most:
1. Focus on at least 90 steps per minute with each leg. Particularly if fatigued, focus on this
stride rate, which automatically produces the other characteristics of good running
mechanics (landing on the balls of the feet, fast pull, etc.)
