Radio 1 star Greg James to kick off bid for five triathlons in five days at Belfast's Lagan Weir
Radio 1 presenter Greg James has announced he will embark on an epic five-day triathlon for Sport Relief 2016, starting off in Belfast next month.
The 'Gregathon' will see the broadcaster cover more than 50 miles swimming, running or cycling in a different city each day.
He plans to start off by swimming a mile in the cold of Lagan Weir in Belfast Harbour, before cycling 40-45 miles and running another 10 miles. After that, he will do the same thing all over again in Cardiff, Glasgow, Sheffield and Norwich.
Greg will face a total incline of 16,888ft0 while running and cycling, and will have to deal with swimming in winter conditions.
The 30-year-old follows in the steps of other celebrities such as David Walliams and Davina McCall, who respectively completed a 140-mile swim up the River Thames and a 500-mile run around Britain for Sport Relief.
As he announced his challenge yesterday, Greg acknowledged that it would be tough going.
"It will come as no surprise to you that I'm not a professional athlete," he said. "So the prospect of doing one triathlon is daunting enough. Doing five in five days in five different cities is madness.
"I want this to be one of those challenges that no one following would want to do.
"It needs to be genuinely horrible for me so that people buy into it and donate their money to this incredible cause.
"Training has been tough, wet and so horribly cold, but I'm determined to accomplish this so that Sport Relief will be able to direct some much-needed money to support people who really need it.
"I'm also looking forward to the fantastic Great British public's support to keep me going in each city. It's going to be a mad week."
While the public will be able to follow his progress all day on Radio 1, Greg also plans to broadcast his show every day after completing each triathlon.
But before he starts, he will be visiting a nursery in a refugee camp in Jordan. There, the broadcaster will see first-hand how the money raised through Sport Relief is used to help the thousands of displaced families and children.
Greg will also be encouraging the public at home to sign up to the Sainsbury's Sport Relief Games in Belfast, taking place March 18-20.
Money raised from the event is divided up by Sport Relief to help people living difficult lives both at home and across the world.
