Event overview
The Big Half is a vibrant, inclusive half marathon celebrating the diversity of London while raising huge amounts for fantastic causes.
Organised by the team behind the London Marathon, this 13.1-mile event lets you experience parts of the famous marathon route from a completely different perspective, whether you're running for fun, fitness or to raise money for charity.
Highlights
London's community half
Bringing together Londoners of all backgrounds and runners of all abilities, from first-timers to seasoned fundraisers.
Running festival
Expect a party on the streets, with charity cheer points, live entertainment and crowds supporting you every step of the way.
Four London boroughs
Run a traffic-free route through Tower Hamlets, Southwark, Lewisham and Greenwich, enjoying some of the iconic marathon route in reverse.
What are charity places?
Charities purchase official places in The Big Half and offer them to runners who commit to fundraising. These are called charity places, and they’re a great way to secure your entry while supporting an important cause, especially if general entries have sold out.
Benefits of running for charity
Running The Big Half for charity gives your training extra purpose. Along with the motivation to get outside and run, many charities provide fundraising guidance, support and race-day encouragement to help make your event experience even more rewarding. See the Fundraising section.

Every year thousands of runners take part in this event and fundraise for charity! While this is hugely beneficial to the charities it gives the runner advantages too, from supporting a cause that is close to your heart to securing a place in this sought-after event and much more.
Benefits of running for charity
When the going gets tough, your admirers step in! As 'masters of motivation', your chosen cause will spur you on and provide plenty of perks in the process:
Fundraising support
Charities know that raising money is all part of the half marathon challenge, which is why they provide advice, branded materials and a personalised online fundraising page to help the donations roll in. Think videos for social media, branded imagery and testimonials from previous runners.
Training support
Whether this is your first run or your fifth, you'll need to train for it! You'll receive an in-depth training plan with guidance, plus many charities have access to expert coaches and elite runners too, who can provide exclusive tips for your race preparation.
Branded running kit
When you show up in London on the big day, people need to be able to see clearly that you're supporting a charity. Most charities will give you a branded and personalised t-shirt or vest to run in on the big day, and often a training top too.
Support on the day
When you're partway through your run and your energy is flagging, what you need is a boost from cheering spectators to keep you moving. Many charities set up a cheer station along the route, keeping an eye out for you to send up a huge cheer as you run past!
Post-race recovery
Refreshments and an indulgent post-race sports massage are often provided by charities for their runners. This is the perfect way to recover alongside other people who have run for that cause.
Exclusive social groups
You won't be the only person running for that charity, so it's well worth meeting other runners through the charity's invite-only social media pages! You can organise to meet up for training runs, chat with the charity's expert coaches and share tips and stories with each other to keep the motivation levels running high.

Really great atmosphere and great for chasing down that PB!! Would recommend to every runner. Lucy R
It was fun running over Tower Bridge. Lynsey K
It's a great race with a big crowd of runners. Connor D
This is my favourite half marathon. I love the route as it takes in some great parts of London- including Tower Bridge and ends up in Greenwich.
It has great PB potential. Sarah M
I loved the route. Running through parts of London I’ve never visited before. Support was fantastic. I got goosebumps running over London Bridge because the support was so loud.
A great sized medal and a nice T-shirt and food bits at the end. Dan M
It's a flat, fast course with a great atmosphere, fantastic crowds spectating and the medal and T-shirt are very nice. David A
