Runners of all ages braved soaring temperatures to go the extra mile for Sport Relief on Saturday.

The event, at West Oxford Community Centre, in Botley Road, attracted around 400 entrants to raise money for the BBC charity.

The fun run was officially started by Oxford athletics legend, and perhaps the most famous mile-man in history, Sir Roger Bannister.

At 4pm, with temperatures hitting 80 degrees, he sounded the starter's horn.

Sir Roger, who ran the first four-minute mile in Oxford in 1954, said: "I think it's a great initiative. It has not been done before on this scale so all credit to the organisers."

He added: "Once you start something like this, the aim is to make it an annual event."

Ten-year-old Matthieu Marshall, who attends St Barnabas School, Oxford, was among those who ran the mile.

And he managed to talk his parents, Peter and Christine, and his brother Pierre, 12, into joining him.

He said: "I just felt like doing the mile, and getting involved with everyone else and do it for Sport Relief."

Another family who took part in the challenge were the Tews, from Banbury.

Mark and Katie did the mile with their four-year-old daughter Serena.

Mr Tew said: "We decided to take part last weekend. We just think it's a really good cause. You can do it regardless of age or ability."

The Sport Relief mile was part of the West Oxford Community Fun Day and there was plenty on offer to entertain runners and spectators including live music, fire eaters and sports demonstrations.

Run organiser Louise Odell said it had been a fantastic day. She said: "It went really well. Everyone had a great time but it's too early to tell how much money was raised. Four hundred runners was a great turn-out and we were obviously helped by the weather."

More than 400,000 people across the country took part in the BBC Sport Relief event in aid of projects here and abroad.
