Couldn't believe it. My knee began to niggle at 20 minutes mark, focused on my form, slowed a bit then sped up. I checked my iPhone and I was knocking out of the park. The last mile I ran at 9 min 19 second mile pace!!! I monstered it. Went home and signed up for my very first parkrun next week. I'm going to resist the temptation to do a 5k over the next week. I want my very first outdoors 5k to be done at parkrun!!
