Big Dog Back Wood Challenge

Big Dog Back Wood Challenge


July 5, 2025

Come and join us at Hillingdon Athletic Club on Saturday 5th July for the Big Dog Back Wood Challenge!

Run or walk as many laps of the woods as you can in a maximum of 12 hours.

Starting at 8am, each lap will be approximately 4.167 miles! Each subsequent lap will start on the hour, every hour, with the final lap at 7pm. You can start any time during the day and do as many laps as you wish.

There will be a barbecue available from midday and the bar will be open!

Entry to the event will be free, but we ask you to support the club and we will need helpers throughout the day.

Friends and family welcome!
