Irish Life Dublin Marathon 2026 places
Take on the Irish Life Dublin Marathon: a memorable city marathon that starts and finishes close to Dublin’s vibrant centre.
Golden beaches, limestone cliffs, woodlands and more – explore the Gower Peninsula as part of Team Dementia UK.
Take on this truly stunning challenge on the Gower Peninsula in South-West Wales, famous for its sweeping golden beaches, limestone cliffs, wild moors, ridges and woodlands. Walk, jog, or run at your pace on routes from 10 miles to 100km, all while making a difference to people affected by dementia.
From basecamp by the ruins of Penrice Castle, head out towards Oxwich Bay and onto the coast path towards Rhossili. Take in spectacular views of Worm’s Head and walk along Rhossili Bay, onto the Gower Way and back to basecamp at the halfway point. Full 100km challengers will continue to Mumbles and inland through charming villages to complete the figure-of-eight route.
You’ll experience first-class support every step of the way, with plenty of rest stops with medical care and snacks and drinks, before claiming your exclusive medal and t-shirt at the finish line.
There’s nothing like the sense of achievement of completing an Ultra Challenge, knowing that your dedication will give more families a lifeline as they face dementia.

The Ultra Challenge Series, run by Ultra Challenge, is the UK’s number one series of treks and trail runs. Dementia UK is a proud series partner of the Ultra Challenge Series.

Throughout each event weekend, challengers will take on distances from 10km up to 100km, creating an unbeatable atmosphere and real sense of community spirit.
You can choose to walk, jog or run your challenge, with unparalleled event support every step of the way. There are regular rest stops with food and drink; fully signposted routes; marshals on the course and walking with you; and exceptional medical and welfare coverage including massage, hot meals and a huge finish line celebration.

Distance options vary according to each Ultra Challenge. Typical distances are 10km, 25km, 50km, 75km and 100km. The full 100km challenges can be undertaken all in one go or over two days.

Right now, nearly one million people are living with dementia in the UK. Too often, families struggle to find support, leaving them feeling exhausted, overwhelmed and alone.
The funds you raise will ensure more families can access the life-changing support of our dementia specialist Admiral Nurses. Together, we can make sure no one faces dementia alone.

Getting started
Fundraising ideas
Organising fundraising activities alongside your main challenge will help you smash your goal. Here are some ideas:
JustGiving
Setting up a JustGiving page is a great way to fundraise online. Share your link with family, friends and colleagues and watch the donations roll in.
You can use JustGiving to explain why you’re taking on your challenge for Dementia UK, keep track of how much you’ve raised and even share your training progress using Strava so your supporters can see how well you’re doing. The event organisers have set up official events on JustGiving so make sure you connect to the right event on your page.
The more you update and share your JustGiving page, the more donations you’ll receive. Contact events@dementiauk.org if you need more advice.
Gift Aid
If your supporters are UK taxpayers and their donation is voluntary (not proceeds of a sale), we can claim an extra 25p for every £1 donated, at no extra cost to them. Make sure they fill in the Gift Aid form or tick the correct boxes if they’re donating online.
If you’re fundraising through JustGiving and your page is connected to Dementia UK, the donations will automatically come to us. If you’ve got cash to pay in, you can do this online, by phone, by bank transfer or by post
How to pay in your fundraising
Every donation you raise, big or small, will make a huge difference to families facing dementia. Did you know a donation of just £4 to your fundraiser could pay for the telephone costs of one family calling our free Helpline for immediate support?
to run a full day of face-to-face appointments for families affected by young onset dementia (where symptoms develop under the age of 65).
to answer calls on our Helpline on a Sunday, when other dementia services are closed.
for a whole week to support a community where people are struggling to access local dementia services.
