We can either use these 35,000 opportunities to load our body well and create elastic energy to propel us forwards or we can suffer all of that impact, which will in turn slow us down and potentially hurt us.

RULE #6: PRACTICE STEP CYCLES Step cycles take the hard-easy principle to a broader time scale. Also known as mesocycles, step cycles are multiweek training blocks in which the running workload is intentionally varied from week to week. In a step cycle, each week of training is slightly more challenging than the preceding, until the last week of th
