Paula Radcliffe, who missed out on competing at the London 2012 Olympics due to injury, said she is "looking forward" to the National Lottery Anniversary Run later today:
Marathon world record-holder Paula Radcliffe will run the first event to be staged at London's Olympic Stadium since the 2012 Games later today.
Radcliffe, who was unable to compete at the London Olympics due to injury, will join a host of sporting stars including Olympic gold medallists Sir Chris Hoy and Victoria Pendleton, who are more used to cycling than running.
They will be among the 12,500 people taking part in the five-mile (eight-kilometre) National Lottery Anniversary Run, in which competitors will complete the final 328 yards (300m) on the Olympic Stadium's track.
Radcliffe has predicted the event would "recapture the spirit of the London 2012".
Sir Chris Hoy told ITV News Tour de France leader Chris Froome would be "frustrated" by the constant questions on doping but the recent scandal in athletics involving Asafa Powell and Tyson Gay showed the "testing procedures are working well".
The Ministry of Defence has announced that Britain's most successful Olympian Sir Chris Hoy is becoming an Ambassador and Honorary Group Captain for the Air Cadets.
Last week the six time Olympic champion announced his retirement from competitive cycling.
Chris Hoy's wife Sarra paid tribute to her partner on Twitter, writing:
Sarra, who married Hoy in Edinburgh in 2010, said they would be toasting his retirement later.She joked:
Britain's most decorated Olympian, Sir Chris Hoy, has described being "lucky" to be part of the London 2012 Olympics and said he will enjoy being a spectator at the 2014 Commonwealth Games in Glasgow.
