If your running shoes have been gathering dust like a forgotten gym membership, consider this your polite (but firm) nudge: the Royal Parks Half Marathon ballot for 2026 opens today, 26 January 2026, and the appetite is expected to be ravenous after record-breaking entries last year and a “blockbuster” 2025 event. Londoners love a queue, after all — ideally for something that ends with a medal and a post-race snack the size of a small ottoman.
Now in its 19th year, the race has come a long way since it was first launched in 2008 by The Royal Parks charity as a fundraising initiative. These days it’s less “just a run” and more a moving festival of human optimism: first-timers chasing a personal best, charity heroes collecting sponsorship like it’s loose change, seasoned half-marathoners doing that suspiciously calm “I’m only jogging” routine, and families providing sideline support in the form of cheers, banners and the occasional emotional ambush.
When is the Royal Parks Half Marathon 2026?
Circle it, highlight it, tattoo it on your training plan: Sunday, 11 October 2026 is race day. The attraction is obvious — 13.1 miles of London at its most cinematic, wrapped in closed roads and a festival-style atmosphere that makes even the sternest commuter consider a smile.
The route: four Royal Parks and a greatest-hits tour of London
The Royal Parks Half Marathon route threads through Hyde Park, The Green Park, St James’s Park, and Kensington Gardens, then sweeps past a roll-call of landmarks that reads like a postcard rack having an argument: Buckingham Palace, the Houses of Parliament, Trafalgar Square, and the Royal Albert Hall. It’s one of those rare races where you can be gasping for oxygen while simultaneously thinking, “This is actually rather gorgeous.”
One of the UK’s greenest major half marathons
The event has built a reputation as one of the UK’s greenest major half marathons, with sustainability efforts that go beyond a bit of worthy messaging and a recycling bin hidden behind a banner.
Among the sector-defining initiatives: a separate ballot for those residing outside the UK to help reduce event-related travel emissions; the removal of single-use plastic bottles in favour of water refill stations across the event; and compostable cups at water points. Even the bling has a conscience — runners receive medals crafted from FSC-certified wood.
And then there’s the wonderfully British concept of doing something good while slightly denying yourself something nice: the popular ‘Drop the Finisher Top’ initiative. Instead of a finisher T-shirt, participants can choose to plant aquatic plants along the edge of the Serpentine Lake — a stunning part of the route and, frankly, a far better legacy than another top destined to become “painting-the-kitchen attire”.
The fundraising numbers are staggering — and still climbing
Since 2008, the race has helped raise over £80 million for more than 1,900 UK charities. That includes national organisations such as Great Ormond Street Hospital Charity, Mind, MacMillan Cancer Support and Prostate Cancer UK, plus hundreds of local grassroots causes that rely on community fundraising to keep doing what they do best.
Importantly, the impact also lands right under your feet: funds directly help protect London’s Royal Parks, keeping these green spaces thriving — not just as pretty backdrops for Instagram, but as genuine, shared sanctuaries for everyone who needs a breather from city life.
Celebrity runners and race-day sparkle
Last year’s event attracted a celebrity cast list that could make your group chat do a double-take: presenter Jenni Falconer, former footballer John Terry, TV personality Jake Quickenden, The Traitors star Minah Shannon, and actors Adam Woodyatt and Stephen Mangan. Details of the 2026 celebrity lineup will be announced closer to race day, which is a polite way of saying: keep your eyes peeled, and try not to trip if someone famous overtakes you.
What the organisers are saying
Head of the Royal Parks Half Marathon, Liz Tack, said: “The Royal Parks Half Marathon continues to be such a special race for so many people. The atmosphere across the parks on race day is always electric, and paired with our uniquely beautiful route, it creates an experience that stays with runners long after they cross the finish line.
“We’re incredibly proud to have raised over £80 million for more than 1,900 charities since the event began, and we’re excited to build on that impact again in 2026 through the amazing fundraising efforts of our runners. Good luck to everyone entering the ballot and we can’t wait to welcome thousands of you back!”
