Plymouth-based Army captain dies after collapsing during the London Marathon

A runner who died during yesterday's London Marathon has been identified as an Army captain based in Plymouth.

31-year-old David Seath collapsed at 23 miles - just three short of the finish line - from a suspected cardiac arrest.

His friends are now planning to walk the final three miles he was unable to cover in his memory and to complete what he started.

It is understood Captain Seath had been based in Plymouth after serving in Helmand province during the conflict in Afghanistan.

Originally from Fife in Scotland he was working as a Fire Support Team Commander with the 29 Commando Regiment Royal Artillery.

He was running to raise money for Help for Heroes and had previously done charity work with several charities to help the blind.

He had raised £500 for the veterans charity and thanked his supporters in his final online message before the Marathon:

A fundraising page has now been set up in his memory by a friend and colleague with the aim of "finishing what Dave Seath started for Help for Heroes because this was the charity that he ran and died for."

The page - set up by James Walker-McClimens - has already raised more than £5000 after less than 24 hours.

In a short tribute on the fundraising page David Seath was described as "our friend and hero".
