More than 100 runners tackled the Belfast Marathon on Monday in memory of a Londonderry boy who lost his life alongside members of his family in Donegal in March.
Evan McCrotty (8) had a muscle-wasting condition, Duchenne muscular dystrophy, which is life-limiting and leads to increased disability. Evan's mum, Louise, and Davitt Walsh, who saved Evan's baby sister, Rioghnach-Ann, were among family, friends and members of the community running together as Team Evan.
The group hoped to raise £3,000 towards Muscular Dystrophy UK's ground-breaking research into Duchenne muscular dystrophy.
Members of Team Evan took on the relay race, or covered the full marathon distance, to raise vital cash for the charity's Duchenne Research Breakthrough Fund.
They wore specially designed t-shirts, featuring Evan and his older brother, Mark (12), who also lost his life in the drowning tragedy in Buncrana.
Thomas McCallion, who co-ordinated the group, told how his son Tom (8) asked him to take up the challenge in memory of Evan - his best friend. "Following an effort from my own running club members to run the Belfast Marathon in support of the family, I spoke to my family about possibly doing something myself," he said.
"My son Tom, who was Evan's best friend, asked if I would do the full marathon in his memory - a request I couldn't say no to.
"My own club runners and members of other local clubs in Derry and Donegal have showed fantastic support. It has been a memorable day."
Louise, Evan's mum, said: "I want to thank everyone who took part to remember Evan, whether you ran the race, or donated.
"You did something remarkable in his name and to celebrate his life. I know he would be proud."
