Alternate Run Study

Runners will perform a variation of workouts, consisting of interval/speed work, tempo runs, and long-slow distance runs throughout each 7-day period

Runners will be assigned identical training sessions over a 7-day period but will alternate use of two different models of running shoes across successive workouts (Nike Pegasus and Nike Zoom Streak). The Zoom Streak has 10mm less midsole material, a less supportive heel counter and more flexible forefoot providing a more responsive feel to the runner.

Runners will be assigned identical training sessions over a 7-day period.

Runners perform runs in two pairs of the same assigned neutral-cushioned running shoe (Nike Pegasus).
