Notes
Temperature pretty good, not too much sun, a bit of wind. Started off really sluggish and just couldn't hit pace, was afraid to exert myself too much too soon. Eventually started picking it up and by the 3rd km was in full on tempo mode. Pushed it a bit in the last couple of kms but never reached my limit nor slipped out of tempo breathing. Still had DOMS and left calf still pretty tight but neither really bothered me too much during the tempo.
Last mile at 3:56 pace
