The money raised will help tackle issues such as homelessness, domestic abuse, mental health stigma and child poverty. Each competitor has their own personal motivation, which will be revealed along the way.
The challenge will kick-off in Cardiff on Wednesday 11th March, followed by a trip to Glasgow on Thursday 12th March, before the trio head to Manchester where they will complete their third triathlon in as many days, on Friday 13th March, the day of Sport Relief.
