A great event to wrap up and walk off the Christmas & New Year celebrations; maybe kick start a new fitness regime – and to fundraise for your favourite charity! There are Full Marathon, Half Marathon & 10km distance options – and an accessible ‘Family Fun 5K’ on the Sunday. All routes start & finish at The Oval Cricket Ground, and take in highlights of the Thames, its historic bridges, and many of the Capital’s landmarks. Sign up as a team, or as an individual and families are welcome. There’s rest stops with snacks & drinks, a special medal, and hot food back at the finish before you head home.
Pink arrows mark the route, with distance markers, glowsticks after dark, and a Google map via the App just in case! Our experienced Trek Masters are out & about to provide support, with a timing system enabling the Control Room (& friends / family) to monitor your progress & finish times. We have medics at the rest stop venues to deal with any aches / pains or blisters.
It might be chilly so there’s a special Winter Walk bobble hat which is FREE with the Early Bird Deal – and picked up on the day at The Oval start)
New Year diets may still be on track for some – but keeping energised is important and you won’t go hungry…
Coffee, tea & biscuits at the start
You’ll get a big cheer as you cross the finish line and a well earned Winter Walk medal. Certificates can be downloaded via the event App.
Once you’re signed up, there’s a mobile phone App to download with all the key information, maps, & details of the walk at your finger tips. There’s also an active Facebook Group to share your preparation and winter journey with other Winter Walkers!

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.
