London 2 Brighton
Ultra Challenge®

24-25 May 2025

The ‘original Ultra Challenge’ – take it on as part of the Arqiva Challenge and  fundraise for Children with Cancer. Over 2,000 adventurers will take on the Capital to Coast route and test their grit & determination over the weekend. Richmond-Upon-Thames is the start, and it’s over the North Downs with wonderful Surrey & Sussex countryside to half way at Turners Hill. The full 100 km route heads over the South Downs before the welcome sight of the Brighton coastline comes in to view. You’ll get full support & hospitality all the way – and with three quarter, half, marathon & quarter distance options also available – there’s a classic challenge for everyone!

The Ultra Challenge® Experience

UK’s #1 Endurance Style Events for ALL Experience Levels.

Choose your Challenge, support your charity – do it at your pace, and there are 20 events in the Series with distance options to suit all! The ‘famous’ Ultra Challenge support enables you to go further, whilst enjoying the great outdoors & camaraderie. There are marquee rest stops, lots of food & drink, medical & massage teams, with a fully signed route to guide you. A big finish-line celebration awaits with an amazing sense of achievement, and once the aches subside you’ll feel energised, and up for more of life’s real challenges! 

Push Yourself Further in 2025

Good preparation & smart planning are key, and from the moment you sign up you’ll have access to our Challenge App – with training guides, optional training walks, maps, online forums, and the latest news & updates.

Rest Stops every ~12.5 km with ‘major’ ones every ~25 km, and are much more than the shaky gazebo with water that you see on some events. We’ve marquee cover, large medical & welfare tents, catering services, seating areas for recovery, changing rooms, and a friendly welcome!

There’re pink arrows to guide you, distance markers, glow-sticks at night, hazard signs, and a route map in the App. Our ‘Trek Masters’ organise group departures at night so nobody has to walk solo. Our chip timing system enables our Control Room, and your friends / family, to track your progress through the Rest Stops.

Keeping you well fed & hydrated is key. We pride ourselves on the quantity & quality of our catering, and meals, snacks & drinks are included!

  • Snacks & drink stops every 12.5 km
  • Snacks – from the healthy to treats
  • Picnic at 25 km (for 50km participants)
  • Energy drinks
  • All dietary requirements catered for
  • Lighter options for ‘runners’
  • Finishers hot meal 50 km (picnic for 25km & 10km)

We’ve experienced Doctors, Paramedics, First Aiders, Podiatrists, and Massage Teams at Rest Stops. There’re ‘Self Help’ areas with blister plasters, talc, Vaseline, and tape if you want to patch your own feet. Our mobile Emergency Medical Teams are only a phone call away, via our 24 hour Control Room

We don’t want you to forget that finish-line moment – our Cheer Squad will ensure you won’t! You’ll get a medal, finisher’s T-shirt, and a glass of fizz, before heading to a BBQ and a well earned rest. Download your official Challenge certificate when you’re ready.

There’re shuttles to local train stations for onward travel, and most finish lines have parking so supporters can meet you. We’ve bus ‘transfers’ to / back to key venues (eg the start) – and check out the ‘Bookable Extras’ for details of all transport options.
