Notes
very strong workout, possibly too hard though, would have liked HR 3 beats lower for each interval. Goal set of 3x10+2.5 at slightly faster than HM pace.
@7:19/166 (mostly head)
@7:16/170 (50/50)
@7:04/173 (mostly tail)
Exact same workout from March 5 2015:
@7:25/163 (headwind)
@7:22/167 (tailwind)
@7:12/169 (mixed)
