I have three Something of Substance (SOS) workouts this week. That’s a Hanson’s Marathon Method construct, consisting of speed or strength runs, tempo runs and long runs. In week three of Boston training, I have all three. Tonight is speed work at the Cretzmeyer Track. Thursday will be a tempo run: eight miles, six of which will be at 7:57/mi. Sunday will be a long run of ten miles at 8:40/mi.
