This year, Cora, Vivian, Sabrina and Caroline (aka the Cheeky Chocolate Champions) are taking on a really exciting challenge with their school friends, and thousands of others across the country.

By swimming (50m), cycling (1km) and running (0.75km) in a relay with their team, they will be raising money for Restless Development and Beaudesert Park School's chosen charity, The Oscar Foundation.
