Just graduated this morning with my second parkrun, and shaved 1.5 minutes off my best time to come in at 31'52". Feels great to have achieved it, and like so many here i really didn't think I could do this at the start of the program.
I'm in for some surgery at the end of this week (which was one of the reasons I started this) so will have an enforced break for a couple of weeks, but running will be part of my recouperation plan.
If you are just starting this road, trust the app, it will get you there!
