The plan was simple: rock up to Greenwich Peninsula parkrun, guide a visually impaired runner round, job done, GG task accomplished. But when we arrived at quarter to nine, we discovered it had been was called off because of thick fog. Apparently even the sighted runners would have needed a guide! We weren't going to let a bit of weather beat us though, so we fled North Greenwich in search of the closest parkrun that was actually happening.

Thankfully nearby Southwark parkrun had no qualms about the weather and we jogged into the park just in time to hear the start from afar. With warm encouragement from the volunteer team we were pointed in the direction of the tailwalker who we soon managed to overtake (and even lapped near the end!). So the guiding went ahead as planned, just in a different postcode from the one on the session page.

Purists may point out that this technically wasn't Greenwich volunteering. We'd say the intention was 100% Greenwich, the effort was 100% real, and in that fog nobody could see the borough boundary anyway!

Lesson learned: always check (and re-check) the cancellations page, and keep a backup parkrun in your back pocket. Many thanks to Southwark for the warm welcome. Greenwich Peninsula, we'll see you next time, hopefully when we can see you!
