got up early again and tried to run but started to feel a hint of something in my left heel. similar to the problem i was having last year when trying to run in the morning. cut if off after a half block.
UPDATE: felt fine in the evening so off i went.
- km repeats
-- warm up
-- 1 km @HM pace x (4:20, 4:20, 4:19, 4:19, 4:21, 4:21), 90s jogging rest between reps
-- cool down
cut it off right at 10 km and walked the rest of the way home. this was pretty hard but not killer. 4:20 is like a 1:31:30 half marathon, so not even quite as quick as i'd like to go in september. long way to go. does make me doubtful that i'll be able to run sub-20 in a couple of weeks.
