Thames Path
Ultra Challenge®

14th September 2024

Join The National Brain Appeal as we celebrate our 40th year of transforming the lives of people with neurological conditions!

The National Brain Appeal is the charity dedicated to raising money for Queen Square – a world-leading centre for the treatment and care of patients with neurological and neuromuscular conditions including brain tumour, dementia, epilepsy, MS, Parkinson’s and stroke. Over the past four decades we’ve raised £56m to advance treatments and fund pioneering research into these conditions. 

On 14 September 2024, we’d like to mark this special anniversary by walking either the first 28km, or really  push yourself and tackle the Full 100km route of the Thames Path Challenge over 2 days together with our supporters to help us build on the successes of the past few decades and raise more funds to change the future of neurology. 

See below for more details – and please sign up to the event via the links on this page.

The Ultra Challenge Experience

Endurance events for a wide range of fitness & ages – and UK’s #1 series of treks & trial runs. Choose your Challenge – do it at your pace, and there’re 14 events in the Series. Our support enables you to go further, whilst enjoying the great outdoors & camaraderie. There’re 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!

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. There’s also the option to hire a ‘GEO TRACKER’ – so they can follow you in real time every step of the way – day & night!

Keeping you well fed & hydrated is key. We pride ourselves on the quantity & quality of our catering, and whichever distance you are on – meals, snacks & drinks are included – so no need to carry much!

  • Snacks & drink stops every 12.5 km
  • Snacks – from the healthy to treats
  • Meals / food every 25 km
  • Energy drinks
  • All dietary requirements catered for
  • Lighter options for ‘runners’
  • Finishers meal

We generally have a ~50 km campsite for rest & sleep if you’re on the 2 day ‘Daylight’ 100 km option, or if you finish / start a 50 km ‘half’ Challenge. Book an inclusive package or ‘pitch your own’ – there’re showers and chill out areas.

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 finishers meal 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.
