Tough Mudder 2026

Take on Tough Mudder for Team Terry

Think you've got what it takes?

Take on the Tough Mudder series in 2026 and experience an unforgettable challenge packed with mud, obstacles, teamwork and adrenaline.

Climb walls, crawl through mud, tackle icy water and overcome obstacles designed to test your strength, resilience and determination. Whether you're taking part with friends, colleagues or solo, Tough Mudder is all about pushing your limits, supporting each other and having fun along the way.

Every obstacle you conquer and every pound you raise will help Terrence Higgins Trust support people living with and affected by HIV, challenge stigma, and work towards ending new HIV cases in the UK.

Our dedicated fundraising team at Terrence Higgins Trust is here to support you every step of the way. Whether you're new to fundraising or looking to maximise your impact, we can advise you on the best fundraising platform for the event.

Each Tough Mudder event has its own fundraising target. Before registering, we encourage you to make sure you're comfortable with the fundraising commitment and excited to take on the challenge.

Reaching your fundraising target helps ensure we can continue delivering vital services and support for people living with and affected by HIV.

If you have any concerns about fundraising at any point, please don’t hesitate to contact us at [email protected]. We’re always happy to help!

Your fundraising helps fund essential services, including our sexual health information service, HIV testing, counselling, peer support programmes and campaigns to tackle HIV stigma.

Together, we're working towards a future where:

• There are no new HIV cases in the UK
• Everyone living with HIV is diagnosed and accessing treatment
• Nobody experiences HIV-related stigma or discrimination
• Everyone affected by HIV can access support, information and care

Stand with us. Take on the mud. Help end new HIV cases in the UK.

Every donation helps us support people living with and affected by HIV.

• £15 could help answer a call to THT Direct, our sexual health information and support service.
• £50 could help provide a vital grant for someone living with HIV struggling to afford basic necessities.
• £100 could help fund our Living Well services, helping people living with HIV access support, information and care.

Thanks to the incredible support of our fundraisers — including our challenge event runners — last year we were able to:

• Respond to 12,591 enquiries through our free THT Direct helpline
• Distribute over 5,700 HIV self-test kits at no cost to those who needed them most
• Cover the cost for 500 people living with HIV to access My Community, our secure online space
• Win the case to extend opt-out HIV testing to 89 hospitals across England
• Deliver over 278 Positive Voices sessions, reaching more than 21,100 people with powerful stories about living with HIV

If you're lucky enough to secure your own place, we’d love for you to join our team and fundraise to help end new cases of HIV in the UK by 2030.

There’s no minimum fundraising commitment – we simply ask you to raise what you can. You'll receive the same amazing support from our dedicated team. 

Let us know you have a place.
