Notes

The running workout today is 3 sets of 600 m, 300 m, and 150 m. You will rest 1:00 between reps and 2:00 between sets.

The 600s should be :03-:05 slower than your 400 pace from last week. For example, if your pace for last week was 2:00/400, your 600s should be around 3:04-3:08 (2:03-2:05 400 m + 1:01-1:03 200).

Your 300 m runs should be the same pace as your 400 m runs.

The 150 m should be :03-:05 faster than your 400 m runs. For example, if your 400 pace was 2:00, you should aim to complete your 150s in less than about :56-:58.
