Amazing Sport Relief challenges

They've pushed themselves to the limit all for a good cause - TV and sport stars have been taking on tough challenges to raise money for this year's Sport Relief.

Top BBC radio DJ Jo Whiley completed a 26-hour stint on a treadmill, CBBC's Radze swam a mile across a freezing cold lake in Cumbria.

Davina McCall raised money by running, cycling and swimming from Edinburgh to London in just seven days.

Radio 1 host Nick Grimshaw completed a 12-hour bike ride after he, along with other celebrities, cycled more than 1,000 miles and ex-footballer Robbie Savage beat former England captain Alan Shearer in a race to sit on all 90,000 seats in Wembley Stadium!
