Ready for an epic tree-planting challenge? Take on our BIG 100 monthly challenge.

Run, walk or wheelchair race 100 miles or kilometres within a month from the date you sign up and we’ll plant a whopping 15 trees for you. Your trees will grow to support over 5000 living creatures and provide enough oxygen for 30 people! This challenge can be completed in stages. Simply upload photos of your evidence at the end of the challenge.

Entries will need to be submitted within 5 days of the end of your month to be counted within the race. We’re sorry, but submissions after the closing date will not appear in the race results. Race results will be available within 3 days of the closing date. Your seeded medal, if you’ve ordered one, will be sent within 5 working days of the closing date by 2nd class post.
