RUN THREE 1200-METER REPEATS: It's another day at the track. Today we're doing "strength intervals": longer intervals to build leg strength. Warm up, then run three 1200-meter repeats at your goal 10K pace. Rest for two minutes between repeats. As we've said, most tracks are measured in meters, with one lap equaling 400 meters. So a 1200-meter run is three laps.
