Commute in extended from 11.5km to HM distance. Left hip flexor made itself known at about mile 7 but wasn't painful enough to stop (guessing it's just a bit tight from 5-a-side last night, as was my right calf which took a kick) so I slowed a bit to be on the safe side.
Trudged through in 2h22 with HRavg almost 20bpm below that of my PB for this run. Now being paid to recover at work whilst I dribble into my keyboard.
Also doing The Big Half. Hoping to scrape round in a new PB (2h06).
