Notes
2 x 1600m, 2 x 1000m, 2 x 600m, 2 x 400m @ 10k/5k/3k/mile pace with 2:30/2:15/2:00/1:45 rest. Splits were 4:55, 4:57, 2:53, 2:54, 1:36, 1:34, 61.9, 61.2 Felt a little sluggish during the 1600s but switched directions after that and it literally turned the workout around — felt really good the last 4 reps.
