Transport for London, the organisers of this Sunday’s Hovis London Freewheel bike ride, had to close registration for the event two weeks early due to over-subscription.

Lured by the spectacle of riding through central London on completely traffic-free roads, 40,000 people have now signed up to ride the 14 kilometre route.

Many more are expected to turn up on the day – and there’s nothing anyone can do to stop them as the event is on public roads. Numbers of riders turning up on the day could easily double the official registered figure. It will be, without a doubt, the biggest bike ride the capital has ever seen.

As well as the ride itself, the Freewheel Festival kicks off from midday in St James’s Park, featuring a ‘cycling circus’, stalls, bicycle maintenance demonstrations and much more. Entry to the festival is free.
