I cannot recommend this enough after doing it last night, 400+ people running through Finsbury Park for 5 and 10K.
There is support, marshals, post run drinks, medal etc.
Makes for a really inspiring run whether you do it in 15 minutes or an hour, I managed to take a minute off my Parkrun time from Saturday.
Apparently at the Wimbledon one the medal is in the shape of a Womble!
Coincidentally there was over 400 people at Parkrun on Saturday as well.http://www.runthrough.co.uk/?event=chase-the-sun-summer-series-pass-2017
