The Sport Relief Radio Assault challenge
Radio 2's Matt Williams, 5 live's Rachel Burden, Radio 3's Tom Service and Radio 4's Jane Garvey
Last Friday 5 live’s Rachel Burden took on six other BBC Radio presenters in the Sport Relief Radio Assault challenge.
The Sport Relief seven were timed along a wet, muddy one-mile course all in the name of charity – and a bit of healthy inter-radio network competition, of course.
Lines are now open for people to vote for who they want to win: the person with the most votes gets seven minutes knocked off their time, the second six minutes and so on. None of the participants know how well they’ve done.
You can look at photos of Rachel tackling the course in this gallery.
Remember, it's not too late to sign up for your own Sport Relief mile. Full details can be found on the Sport Relief website.
