Take on Spectacular World Heritage coastline – and fundraise for your favourite charity. A start in Corfe Castle, the route heads down to Swanage, and along through Lulworth Cove, past Durdle Door, with ups & downs to Weymouth half way. For full 100 km challengers, it’s past Portland Bill, Chesil Beach, and on to West Bay (of TV’s Broadchurch) – before a finish line celebration in the vibrant town of Bridport. Great 3/4, Half, a Weymouth Marathon & 1/4 Challenge options also – PLUS the Bridport 10K – it’s the event of the year!
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!
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!
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.

(NOTE– If you don’t receive that e mail within 12 hours, please check your spam/junk mail folders)
You can expect to hear from your charity within 14 days. If for some reason you do not hear from them – please contact them directly, and also email us at charity@actionchallenge.com & we will follow up with the charity for you.
We ensure that registered teams are assigned the same start wave (where distance/challenge option allows), and your team name will be printed onto your bib.
There are no restrictions on our regular teams – you can be any mixture of charities / distances / funding types (i.e. Self Funding, Charity Sponsorship or Mixed Funding), and can have any number of members. (even 2).
Even if you are not fundraising for the same charity, you can still create a challenge team with us.
Whilst you are signing up and registering for your challenge – in the TEAM INFO section (towards the end of the registration questions), you will be asked if you would like to ‘Join a team’ or ‘Create a team’.
If selecting to create a team, you will be asked to create a Team Name and Password. Subsequent team members can then register and select to join your team, and will need to provide the team password in order to join it.
Yes – as long as you are fundraising for the same charity, you can create a team fundraising page on Just Giving (we recommend letting your charity know this is how you will be fundraising together). However, please be advised that the minimum fundraising targets remain per person (not per team), so you will need to reach the combined total fundraising amount on your page for your group.
If you are entering on a Charity Sponsorship or Mixed Funding place then NO – you must select one prime charity for your fundraising. This is because your charity will be paying for a portion of your place on the event (out of the fundraising that you generate). If you wish to also fundraise for another charity, you can do so on your own terms but only as long as you reach the minimum fundraising target your first/prime charity.
If you join as ‘Own Place Charity Fundraising’ however, you have complete flexibility on who you fundraise for – with no targets or deadlines.
All sponsorship goes direct to the Charity via your online JustGiving page – WHICH YOU MUST SET UP.
At least 50% of the ‘sponsorship target’ should be with the Charity 3 weeks prior to the Challenge. At this time the Charity agrees to pay a Fee for your place to the Ultra Challenge Organiser (similar to the Self Funding cost – or half of it for Mixed Funding as you’ve already covered half).
Failure to meet the deadline may result in cancellation of your place by your charity.
The remaining 50%, and any extra, should be with your Charity by 4 weeks after the Challenge.
All charity sponsorship and mixed funding places close 4 weeks before each challenge, so that you have enough time to fundraise and reach your target. Self funding places close for online registration on the Tuesday before each challenge.
