About the event
Introducing The Copthorne Heavy!
A 48hr Backyard style Ultramarathon.
The Copthorne Heavy is our take on the classic backyard ultra format, simple in theory, increasingly brutal in practice.
Starting at 6:00pm on Friday, runners set off to complete one full Copthorne loop every three hours. Finish the loop inside the time limit and you earn the right to start the next one. Any spare time is yours to eat, rest and sort your kit before the bell goes again.
