Kevin Sinfield struggles to hold back the tears as he pays an emotional tribute to rugby player Doddie Weir at the end of day four of a gruelling week of challenges.
The rugby league star is raising money to support those affected by motor neurone disease (MND) and it running an ultra-marathon every day for seven days in seven cities in December.
Sinfield set off on a 27-mile run to Edinburgh from Queensferry on Monday (4 December) and said the race in the Scottish capital is a tribute to former rugby star Weir, who died from MND last year.
