Radio 1 DJ Nick Grimshaw has completed a 12 hour bike ride for Sport Relief.

The presenter's challenge took place in a large, transparent box outside BBC Broadcasting House, and he was joined by other celebrities throughout the day, cycling more than 1,000 miles and raising more than £115,000 for charity.

Speaking shortly after completing the ride, he told BBC News that his experience of seeing how the money would be spent had motivated him.
