Went to Bedfont Lakes for my first parkrun today, a bit nervous about the run and not knowing anyone there. Turns out I shouldn't have worried about either. There was one other first timer and we were given our own briefing by Sophie who explained the course and what we should do at the end of the event.
My target was to complete the 5K without having to walk, rather than trying to target a time and I did it without coming in last as well!
So if you're thinking of giving parkrun a try, I can thoroughly recommend it - looks like I'll be going back again soon
