Notes
4 x (400m @ 80, 50s jog)
Final jog can be 1-2 mins to get out to roads
3M Tempo @ 6:15 and building (can be faster!)
1-2 min jog back to track
4 x (400m @ 80, 50s jog)
Windy day, and the last 1.5 was into the wind. Managed to maintain the effort, and the last mile was doable. Felt a little quad tightness in some of the last 400s.
