Friends of an Arbroath man who collapsed and died three miles short of the London Marathon finish line want to “complete what he started”.
Captain David Seath, a fire support team commander in 29 Commando Regiment Royal Artillery, suffered a suspected cardiac arrest while running the 26.2 mile course on Sunday.
He was taken to hospital by the London Ambulance Service but later died.
Mr Seath had been running for the charity Help For Heroes because he said on his fundraising page “the forces community need our help and continued support”.
Friends and colleagues of the Army captain are now vowing to “complete what he started” – finishing the marathon course for him and continuing to raise cash for his chosen charity.

In a JustGiving page created by James Walker McClimens, it reads: “He was three miles short of the finish line and collapsed on Upper Thames Street.
“His friends and colleagues are planning to complete what he started, in his honour. We will walk as one, the final three miles of the marathon, starting where he fell.
“We’re raising money for Help For Heroes, a cause he ran and died for. He was our friend and hero. Please share this page far and wide.”
Mr Seath completed two masters degrees at the University of Aberdeen before joining the Royal Military Academy Sandhurst in 2009.
Before the run he posted on his JustGiving page: “A big thank you to everyone that has been so generous and sponsoring me for tomorrow.
“I am sure H4H will be equally as appreciative. Every penny counts and to have broken the £200 mark with your help is very special. Thank you all so much.”
Since his death the total on his JustGiving page (https://www.justgiving.com/David-Seath-London-Marathon) now stands at more than £812.
In a statement, organisers of the London Marathon, said: “With deep sadness, we confirm the death of a participant in the 2016 Virgin Money London Marathon.
“David Seath, a serving officer in the British Army, collapsed at the 21 mile mark and, although he received immediate medical treatment, he died later in hospital.
“David’s parents Libby and Pete, his brother Gary, his girlfriend Gabby Judd, and his aunt Morag paid tribute to David and welcomed donations in David’s memory to his Help for Heroes fundraising page.”
Libby Seath said: “David has achieved more in 31 years than most people do in 70. He lived his life on the edge and to the full. He was running to raise money for Help the Heroes, a cause which was very important to him.”

Lieutenant Colonel Jon Cresswell, Commanding Officer of 29 Commando Regiment Royal Artillery, paid tribute.
He said: “The Regiment was devastated to learn of the tragic loss of Captain Dave Seath during 2016’s London Marathon.
“Dave was an outstanding commando officer, a natural leader and a true gentleman. He was my Assistant Adjutant and so I knew him very well.
“He served on operations in Helmand with 19th Regiment Royal Artillery before joining the Commando Gunners and earning his green beret.
“Witty, charming and polished, Dave was a fabulous host and stylish performer. As such he was the obvious choice to lead the Blue Peter Ten Tors team last year.
“Selected to train the future officers of the Afghan National Army later this year in the rank of major, Dave had a great career ahead of him.
“The thoughts of the Regiment are with Gabby and Dave’s family and friends at this tragic time. We have lost one of the great characters of our Regiment and take strength from the memory of his example and leadership.”
