UK’s No 1 Series of treks & trail runs! Take on a challenge at your pace and fundraise for your favourite charity! Whether along a stunning coastline or on trails through magnificent countryside, you’ll get full support all the way – including plenty of food & drink, medics & massage, camaraderie, a medal & T shirt - and an amazing sense of achievement. With 20 events to choose from, and distance options ranging from 10 km up to the full100 km – there’s an Ultra Challenge waiting for you in 2026.
Many people with MS take part in Ultra Challenges without any problems, but this can be a physically demanding event so you do need to be generally fit and have a good level of mobility. If an Ultra Challenge isn't for you, perhaps you might be interested in one of our other events such as Miles for MS.
We'll keep in touch in the run up to your event and so if it looks like you might need to give your fundraising an extra boost, or if you might need some more time after the challenge to reach your target, we'll be there to help. We can discuss different tips to boost your fundraising or even maybe help you to plan an event.
There is a minimum sponsorship amount as we have to pay the costs of your place from what you raise in advance of the challenge. You'll have to have raised 50% of your target 3 weeks before the challenge weekend and we know that it can sometimes be tough to raise this much so far before your challenge starts. That's why we'll help get your fundraising going right from the moment you register.
There are three different fundraising options for these events:
1) Full charity sponsorship option - pay a small registration fee and then fundraise with a set target for MS Trust (we'll cover the rest of the cost of your place)
2) Mixed funding option - pay for half your place cost and fundraise with a smaller target for MS Trust (we'll pay half of your place cost)
3) Self funding option - pay for your place and then fundraise whatever you can for MS Trust with no set target (we won't pay anything)
Exact fundraising targets and registration fees depend on the distance chosen and can be found by following the link for each event.
You must be 18 or over for a Full Challenge (~100km); 16+ and accompanied by an adult for a Half Challenge (~50km ); 14+ and accompanied by an adult for a Quarter Challenge (~25km) or Marathon); for a Half Marathon aged 12+ and accompanied by an adult; and finally 8+ & accompanied by an adult for a 10km/mile Challenge.
Under 18s taking part must be signed up by someone over 18.
