Virgin London Marathon place
Every year tens of thousands would-be London Marathon runners are turned away for lack of space, such is the popularity of this, Britain's biggest participatory sporting event.
The Virgin London Marathon is also the world's biggest one-day fundraising event for charities - it raises more than £45 million every year - thanks to the Golden Bond scheme developed by the Marathon for charities and rejected runners.
Under this scheme, charities can buy guaranteed places and offer them to runners who miss out on a place in return for a commitment to raise a four-figure sum, known as a "pledge". Pledges among CRunCH charities range from £1,300 to £2,100.
Most people enter the Public Ballot and hope for the best. Entry into the 2014 Ballot closed in April after 125,000 people had registered. This means that more people than ever before will be rejected when the results of the Ballot are made known at the end of September. Only around one in seven applicants will get the nod in the autumn, with more than 100,000 would-be runners turned away.
Whether you have entered the Ballot or not, you can use the CRunCH site to apply for a guaranteed place with one of our charities. Inevitably, some charities fill their places more quickly than others; if your favoured cause is full, we may be able to offer you a place on a waiting list - or an alternative cause to run for. But you will need to commit to raising the pledged minimum so the sooner you start the process, the better. First though, please see Your Pledge
If you are fortunate enough to have a guaranteed place already, and are looking for a charity to run for, please see Own Place.
