Love parkrun, its the best thing about the weekend for me. It sets you up for your Saturday.
I'm currently making my way through the A - Z of parkruns for the Alphabeteer achievement (i#m aiming for one each month rather than trying to fit them all in as soon as possible), for this you need to take part in a parkrun whose name starts with every letter of the alphabet, A - Alderley Park, B - Birkenhead, C - Chester etc etc
A week or two back I travelled up to Spennymoor (closest one) to take part in the Jubilee ParkRun to bag the J. There are only 4 parkruns in the UK starting with a J, Jubilee in Spennymoor, Jesmond Dene in Newcastle, Jersey Farm daaarn Saarth and the parkrun on the actual island of Jersey.
K is next in a few weeks time, which my closest one is going to be "Kew Woods" in Southport.
If you use parkrun, and you haven't already, I highly recommend the "5K" app (in your local app store), you put in your parkrun number and it will grab all your stats and show your details for all your parkruns and then you can also keep an eye on your achievements (there are lots).
