HUNDREDS of Hounslow residents strapped on a pair of trainers to raise money for charity.
Schools, colleges and sports centres across the borough got involved with Sport Relief to change the lives of poor and vulnerable people all over the world.
On Sunday 300 people took part in a mass stampede around the grounds of Feltham Community College, with the option to run one mile, three miles or six.
Organiser and sports hall manager Ray Coleman said: "About 200 of the entrants did a mile, 60 did three miles and 40 did the six miler. The sun was out and shining, everybody had a great time and everyone was cheering everyone else on."
Mr Coleman said he was not sure of the total raised yet, but estimates it to be in the region of between £4,000 to £5,000. On Wednesday, around 500 primary school children gave their all in an aerobics session at the Brentford Fountains Leisure Centre.
Samantha Sprong, from the Isleworth and Syon School Sports Partnership, said: "Every year we have the Year 3 and 4 sports day but this year it's tying in with Sport Relief so all the 49 schools involved have been asked to be sponsored for an aerobics session between 11.45am and 12.15pm."
A brave instructor was placed on a platform in the sports hall to instruct the crowd of active youngsters.
Miss Sprong said it was too early to know how much had been raised through the day.
