2023 Sign Up Now

Thames Path Challenge
9 - 10 sept 2023

There are 3 sign up options, and you can join as an Individual or as a Team. The steps you need to follow are set out below…

Choose how you want to sign-up, and via an online form*. You’ll need to enter enter your personal details.

  • Option 1 – Self Funding 
  • Option 2 – Charity Sponsorship
  • Option 3 – Mixed Funding (mix of the 2 above)


NOTE  With the Charity Sponsorship Option – it’s up to 50% OFF the Reg Fee if you choose one of our ‘Official Partner Charities’.

* A ‘Platform Booking Fee’ of 2% is applied to all event registrations.

Confirm the challenge distance you’ll take on (Full ~100km / Half ~50km / Quarter ~25km) – and then select a provisional start time slot(actual start times are confirmed 4 weeks prior to the event, and for Teams – it will be as per the Team Captain’s choice).

Everyone has to register as we require personal details & declarations. Within the form you can choose to ‘Create’ or ‘Join’ a Team. Teams can be of any size – members can opt for the same or different funding options, charities, or distances.

  • Create a Team – you become the Team Captain. You need a Team Name, and a Password for others to join. Then invite friends & family to join you!
  • Others join the Team as they register, by searching for the Team Name & using the Password

You’ll need to select a charity  to support if you’re fundraising. 3 categories of Charities are involved.

  • Official Partners – Long term Series & Challenge partner charities. With the ‘Charity Sponsorship’ option – it’s 50% OFF the normal Reg Fee.
  • Associate Partners  –  50 or so charities promoting the Series, and it’s 25% OFF normal Reg Fees for the Charity Sponsorship option. 
  • Listed Charities – 300 or so other charities involved – and the ‘normal‘ Reg Fee applies.

Follow the right link to choose your charity & pay the correct Reg Fee. Be careful to tick the right box, or correct selection from a drop down list. Your confirmation email details how to set up an online JustGiving page for sponsorship donations.

All sponsorship goes direct to the Charity via your online JustGiving page. 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 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.

Multi Deals are the Best value if you’re up for a 2 or more challenges in 2023 and plan to ‘Self Fund’. There’s also the new ‘Payment Plan’ option – to spread the load, stay active and do more Ultra Challenges!

How to Join

Our Series Partners are some of the UK’s major national charities, and there’re also regional and local charities as Challenge Partners for each event. Choose to fundraise for a Charity Partner and they’ll provide support to help you reach your target!

or fundraise for over 300+ others


You will receive a receipt via email, along with a Confirmation Email welcoming you onto the challenge detailing any next steps and timelines you need to be aware of, and letting you know where to find all the information you will need for your challenge. If you don’t receive this within 24 hours, please check your spam/junk mail folders.

If you have already signed up to a Challenge(s) or a multi-deal and now want to take part in another challenge – please complete our application from HERE>>>

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.

Yes you must be 18 or over on the day of the challenge if taking on a Full Challenge, 16+ & accompanied by an adult if taking on a Half Challenge, 14+ & accompanied by an adult if taking on a Quarter Challenge.

For a Half Marathon you need to be 12+ & accompanied by an adult, a Full Marathon you need to be 14+ & accompanied by an adult, and finally 8+ & accompanied by an adult for a 10km Challenge.

Under 18s taking part cannot sign themselves up – they must be signed up by someone over 18.

YES –  there is on ‘Self Funding’ places. Head to the ‘Discounts & Deals’ page / tab for more info – which will give you a great saving!

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.

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 1!)

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 there is a charity you would like to fundraise for that does not appear on our list, we ask that you speak with your preferred Charity about what you would like to, and ask them to register with us via our short contact form which can be found on our website page www.ultrachallenge.com/the-charities/

Once they’ve registered with us, it will take about 5-7 working days to add them onto our registration forms, and you can then sign up to your chosen challenge in aid of them.

Alternatively you can raise for one of the 300+ charities for 2023 challenges we are currently already working with (see our list HERE>>>), or you can Self Fund your place and fundraise for them independently with no fundraising commitment. 

Please note: the above is relevant for Charity Sponsorship or Mixed Funding places only. If you are entering as a Self Funder you can fundraise for any charity of your choice (only if you want to) & we do not need to be informed.

If you are entering on a Charity Sponsorship or Mixed Funding place then NO – you must select one prime charity for your fundraising, and they must be listed with us HERE>>>. 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 a Self Funder however, you have complete flexibility on who you fundraise for – with no targets or deadlines, and no cost to those charities.

If you have chosen to fundraise for a charity (from our list HERE>>>), we will pass your details over to them and you can expect to hear from them within 14 days. If for some reason you do not hear from your charity after this time, please contact them directly, and please complete our ‘non-contact form’ HERE>>>
