20x200m (200m jog) avg 31.5
+ 6x200m (walk across) 29.8, 29.8, 30.0, 29.8, 29.8, 27.3
First 20 reps solo and kept them aerobic, then jumped in with Crem's group for an extra 6 reps. Coincidentally and reassuringly they were doing 20x200m also working aerobically, albeit much quicker than me 30.0s, I did alternate reps with 2min walk recovery.
31.2 seemed to be my aerobic line, each rep quicker was followed with a 31 high. Hope that line moves as I progress through the season.
Feeling great, I'll attempt something fast tomorrow.
