I volunteered at Parkrun on Saturday and got chatting to a very nice lady, as you do! She asked if I knew about the Chrome extension for Parkrun. I didn't. She told me to look it up, said it was fun (in return I told her about healthunlocked ).
So I did. If you use Google Chrome as your browser you can download it free from this link chrome.google.com/webstore/...
You tell it your Parkrun id and it displays your run and volunteer details much like the Parkrun website. But it also has additional challenges - a-z, north - south- east- west, a 'seconds' challenge and more.
Just more virtual badges and trophies, but if you enjoy parkrun tourism you might like it
