Run (Interval) 10:25 [4] 2.4 km (4:20 / km)
Only had time for a short run, so although (or perhaps because) I was thinking how nice a leisurely 30 min run would be, I ran two 10 minute intervals with a 10 minute recovery run in between. Note to self: if the first interval (on the way out) feels like you're flying... question why that is. It's probably because you have a little bit of a tailwind, and much of your run out was on a gentle downhill. Makes the interval on the way home hurt lots more.
Hamstrings have been tight, and were definitely feeling tender by the end of this run.
Run 10:35 [4] 2.4 km (4:25 / km)
Interval on the return end... ouchy, but happy that I only lost a few seconds on the way back, I was hurting pretty good, so I thought it might be more.
