A charity schools triathlon backed by Flight Centre is returning for its third year in 2018.

More than 3,000 children are set to take part in this year’s event, with a fundraising target of £300,000.

Since 2016 more than 3,500 children between the ages of 7-13 have taken part and raised nearly £400,000 for charity.

Around 50 schools from local areas will take part this year, putting together teams to run, swim and cycle at the triathlon events, taking place between April 22 and May 20.

Children compete in teams of four at running, swimming and cycling.

The scheme supports international development charity Restless Development to support young people in communities across ten countries including the UK.

This year’s events will be hosted by Royal Russell School, Croydon; Bradfield College, Berkshire; Cranleigh School, Surrey and Marlborough College, Wiltshire.

Flight Centre UK managing director, Chris Gallanty, said: “Seeing the children put their heart and soul into competing – not only on the field but also in their fundraising – is so inspiring.

“This a brilliant example of what young people can do when they set their mind to it and we are proud to support them and their families.

“We are also delighted by how our colleagues at Flight Centre have thrown themselves into the events as volunteers on the day. It is a reflection of the enthusiasm we see in teams throughout the business.”

Laura Woodhouse, senior fundraising manager at Restless Development, added: “The triathlon is an amazing event, not only because of the vital money it raises, but because it shows young people around the world standing side by side to support each other. The power these young people have to make change is an inspiration.”
