Davina McCall broke down in tears as she completed her gruelling 500-mile (805km) journey from Edinburgh to London.

The presenter crossed the finish line outside Tate Modern at 4.10pm to conclude the final leg of her arduous physical challenge for Sport Relief.

Davina, 46, ran a full marathon distance to round off seven days of running, cycling and swimming for charity.

After her feat was described to the waiting crowd of around 100 people, Davina said: “I can’t believe it was me.

“Thank you to everybody who has donated – that is why I did it – the team that got me here, they carried me through the threshold.

“My kids and my husband were amazing.”

She joked: “I have got to stop crying!”
