Ran my first Parkrun this morning, after having to psyche myself up - I wasn't expecting to be so nervous, but I really was! Everyone was lovely, though, and I (somehow) ran the course in ~26 minutes, according to my watch. I was pretty confused about this - this is the nice surprise bit - but I concluded that if the course wasn't wrong, then my running app must be, since it said that I'd only run 2.8km after completing the 5K.
So that means that when I ran my 43 minute 5k on Thursday, I was probably running a bit more than 5K. So...yay?
