Jessica Ennis has sent her best wishes following his bike crash.
The Olympic heptathlon gold medallist told Channel 5 News: "I saw the news this morning and obviously I just want to wish him well. Hopefully he'll make a speedy recovery and gets back on his bike.
"It is very dangerous and you hear about some horrible accidents, and stories about what happens to cyclists, and I know he's been campaigning about road safety, so it's awful that's happened to him but hopefully he can recover quickly and get back to it."
Really wishing my friend Bradley Wiggins a speedy recovery in hospital after being knocked off his bike by a car yesterday.From @MarkCavendish on Twitter:

Since June 2012 more than 12,000 people have signed up to British Cycling's Social Cycling groups, with 264 groups already being formed around the country.
The National Cycling Centre's velodrome in Manchester was getting 200 new inquiries a day after the Games, compared with a daily average of 20 before the Games.

Cycling is not an intrinsically dangerous activity but there is much more to be done to improve conditions for cyclists on the roads. British Cycling is calling on the government to put cycling at the heart of transport policy to ensure that cycle safety is built into the design of all new roads, junctions and transport projects, rather than being an afterthought.
Bradley Wiggins has been released from hospital after receiving treatment for injuries suffered in a collision with a van.

This collision should act as a reminder to all drivers that we need to be more vigilant particularly when pulling out of entrances and turning at junctions.
With autumnal weather and darker evenings it is essential to check and double check for cyclists, pedestrians and indeed other road users before pulling out.
We need to break down the 'two tribe' mentality on the roads and co-exist in harmony.
