A close friend of mine who has affiliations with Harvard XC just told me about their training regiment. The team follows a normal 2-workout/1 long run training schedule, but supposedly (on top of their 6min/mile easy runs), the team completes a circuit of weighted lifts (bench press, trap bar deadlift, etc.) following each running workout rep. They'll even make regular stops (once every 2-3 miles) on their weekly long runs to complete the circuit in question. Thoughts?
