Friends of a man who died in his sleep last year ran a 10K on Sunday to raise funds for charity.
Tom Glattback, of Buckhurst Way in Woodford Green, and 11 other friends, ran the British 10K London run in memory of Craig Lobo, who died from Sudden Arrythmic Death Syndrome (SADS) in December, aged 22.
The friends from Woodford Green's Trinity Catholic High School and Chigwell's West Hatch High School, used to meet weekly and play football in Repton Park, in Manor Road, Woodford Bridge.
They were raising money for cardiac charity SADS UK, which campaigns to prevent deaths caused by the sudden stopping of the heart.
Footballer Fabrice Muamba is the most famous victim of the condition, after he collapsed on the pitch in 2012, though he was saved through the immediate use of a defibrillator.
Mr Glattback, 23, said: “It was an emotional experience, we all trained so hard for it with about 10 to 15 runs in preparation so we were all ready.
“We started as a group running together but inevitably everyone split up and went their own pace.
“The group has always met up for a kick-about in Repton Park every weekend and that is how I met Craig.
"He was a true gentleman who had time for everyone, and approached life with a smile on his face.
“It was a massive shock when we heard the news in December.
"It was devastating as it is the last thing you expect from a healthy kid.”
A total of £2,846 has been raised so far by the group, and donations can be made here.
