Blaise, Obi, Noah and Lochlan are taking on a Schools Triathlon, in fact the UK's largest sports fundraising event. Competing as a team of four called the Usain Bros, they'll be swimming, cycling and running in this charity event.
On the day, each team member will take part in all three activities before crossing the finish line together as a team. The Usain Bros are proud to be raising money for charity while challenging themselves and supporting an amazing cause.
