TCS London Marathon

With 50,000 runners taking on the challenge each year and around 750,000 spectators to cheer you on, you too could be a part of the world’s most iconic marathons.

Starting in beautiful Greenwich Park in the South East of the city, during the 26.2 mile route you will take in iconic sites such as the Cutty Sark, Canary Warf, the London Eye, the Houses of Parliament, and, of course, across the magnificent Tower Bridge. You finish up in the centre of the city on the Mall, next to Buckingham Palace.

We have charity places available, so whether you haven’t managed to secure your own place within the ballot, or are just looking for a reason to raise money for a worthwhile cause, why not submit your application today for a chance to be a part of #TeamGuideDogs.

Matt's London Marathon story

I chose to run for Guide Dogs UK as in 2011 I got injured playing football and lost the sight in my left eye. I have partial vision but not enough to see any definition and my decision to run was because I am scared of losing my sight in my right eye. I'll continue to raise money for Guide Dogs UK knowing how much of a positive impact they have on people's lives. Fundraising is about having belief in humankind. Don’t be afraid to talk to people and tell them why.
