Build Endurance and Speed With This Mixed-Pace Workout
This mixed-pace workout consists of 3 sets of 1 mile at half-marathon pace, 1:00 walk recovery, 200m at 5K effort, and 2:00 walk recovery. Perform it once during the final 3 to 4 weeks before a goal race. Keep the mile repeats controlled and run the 200s at 5K effort, not all-out. Success depends on returning to a strong endurance rhythm after running fast.
