Greenleaf and Moult take the BallBuster

The CEP Winter Ballbuster is an event steeped in history and tradition – this was the 26th year for the notoriously challenging duathlon event that pits athletes against Box Hill five times. One of the toughest endurance tests in the UK, the event demands an 8 mile run, followed by 24 miles on the bike, with a final, punishing 8 mile run to finish off.
