Does anyone do parkrun ?
I've been running them for about 2 years now, run about 70 and now I get involved run directing.
It's a free, timed 5k run, every Saturday, somewhere near you.
There are nearly 250 venues around the UK (more than 350 worldwide) with roughly 45,000 runners taking part (65k worldwide).
