David Wyeth of Chorlton Runners was just 200m from finishing the 26.2 mile race when his legs gave up

This is the moment a Manchester runner, David Wyeth of Chorlton Runners club, is rescued from collapse on the final 200 metres of Sunday’s London Marathon.

Wyeth - who was running in memory of his uncle who passed away last year - looked to be doomed to failure as he staggered on The Mall, before fellow runner Matthew Rees swooped in.

Rees, running for Swansea Harriers, sacrificed his own time to heave the stricken Wyeth along the last drag, aided by a steward and cheered on by the crowds - including royals William, Kate and Harry.

Rees said “I thought getting him across the line is more important than shaving a few seconds off my time.”

Wyeth told the BBC, "I was frustrated Matthew was giving up his race, I know how important it is."

The pair completed the run in 2 hours 52 minutes 26 seconds, before Wyeth was carried off for medical treatment.

40,000 runners took part in Sunday’s London Marathon, watched by an estimated crowd of one million people.
