I've been slowly ratcheting up the distance throughout April, with a mind on the Great Yorkshire Run in September (10K). I hadn't actually done 10K for a good while so today was a conscious effort to crack it, and to do it in less than an hour. And I did - 10K in 59mins 3 secs. Yay; very pleased about that. Which, now I think about it, is the "5K in 30 mins" yardstick, twice!
