(a) in Melbourne; and
(b) achilles is too sore.
So I just did Thursday's session instead - 80 continuous. Consists of 20min jog, 20min Fartlek (2min on, 1min off), 5min jog, 20min tempo then 15min warm down jog. Quite a bit by the end (20.2km so 3:57 average) with the tempo averaging 3:27's. Happy with that as I felt in control the whole way through. If only my bloody achilles would improve I'd be starting to feel more confident.
Doing all the 1%'ers on the heel now in an attempt to nip this in the bud.
