Family and friends of a soldier who suffered a suspected cardiac arrest during the London Marathon have completed the course in his memory.

Captain David Seath, 31, collapsed just three miles from the finish line on April 24 and was pronounced dead at hospital shortly afterwards.

Mr Seath, originally from Cowdenbeath in Fife, was a fire support team commander in 29 Commando Regiment Royal Artillery.

Following his death, friends and relatives pledged to complete the marathon route in his honour while raising money for his chosen charity, Help for Heroes. So far, the memorial fund has raised £180,000.

A group travelled from Edinburgh to walk three miles from the spot Mr Seath collapsed to the finish line of the marathon route.

After completing the walk on Sunday, Mr Seath's friends published a post on the fund's Facebook page.

It said: "Tonight has been emotional, overwhelming yet inspirational.

"Family and friends took an important step forward tonight by finishing the 3.2 miles David so tragically could not finish.

"Thank you to everyone who joined us in London as well as all those who walked simultaneously across the world. We move forward, as one."
