London's own wheelchair racing star David Weir will try to break the world record for the fastest mile today - aiming to beat three minutes on the 60th anniversary of Roger Bannister's four minute mile.
He is racing as part of the Bupa Westminster Mile event - a one day festival of mile and track racing in the capital. Sir Roger will be there himself to watch the race and present prizes.
Mo Farah will fire the starting gun at some of the afternoon's races - before looking to claim another victory of his own in the Bupa London 10,000 race on Sunday morning.
Paralympian David Weir is hosting a Q&E session this evening to raise funds for his new charity.
The 'Weirwolf' and his coach, Jenny Archer, will be at the event at Kingsmeadow Stadium in Kingston.
The Weir Archer Academy aims to increase participation and social inclusion at grass roots level, give amateur athletes the opportunity to access regular training, train the next generation of elite athletes and Paralympians and create a Centre of Excellence for disability sport.
Paralympic gold medallist David Weir told ITV London that he had thought about launching the Weir Archer Academy at the Beijing Olympics in 2008. Weir said that "we needed to do something for the future".
It came from an idea that me and Jenny had years ago. When I was in Beijing (for the 2008 Olympics) I was thinking about our squad and looking at the other nations. I thought if no one's going to do something I think I should do, and help the next generation as I don't want our hopes to die in this country - I knew I was getting a little bit older. I'm glad that we've not just stuck with wheelchair racing, we've got other sports involved too, although it's mostly athletics.
Paralympics superstar David Weir received a CBE at Buckingham Palace today, after collecting a haul of gold medals at London 2012.
The wheelchair racer from Sutton was unbeaten during last year's Games, winning gold in the 800m, 1500m, 5000m and the T54 Marathon.
After the ceremony, the sportsman recalled his memories of last summer: "It was just a special time for any Paralympian - we knew it was going to be big because it was going to be in our home city, but just to go out and hear that crowd every day was just an amazing feeling."
He added: "It was the first time we didn't feel disabled, we felt like athletes, we felt like Olympians - we felt like we should have been there.
"Seeing that stadium full for morning sessions was just unbelievable, it was just a dream come true. I felt like I was dreaming all the time, I just felt 'This is not real'. I thought someone was going to wake me up and I was going to race into an empty stadium.
"I felt so proud to be British and we pulled that off. You've got to thank Seb Coe and Locog and everyone else for telling us it would be the best Paralympics ever."
