Sign Up Now

Chiltern 50
26 September 2020

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…

How to Join

Sign up via our online form, and pay the appropriate Registration Fee. You'll receive a confirmation email with important details and access to your Challenge App, with the resources to help you prepare. If you choose one of the fundraising options we'll confirm that with the charity you've selected, and they will be in contact to welcome you within 7 - 10 days.

Choose how you want to join the Challenge – register via that option and its associated online form. Then enter your personal details.


  • Option 1 – Self Funding 
  • Option 2 – Charity Sponsorship
  • Option 3 – Mixed Funding

Confirm the distance you wish to take on. You’ll need to chose an hourly start time window (actual start times are confirmed 2 weeks prior to the event).

Everyone needs to register as we require personal details & declarations, but 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 members to join you!
  • Others then join the Team as they register, by searching for the Team Name and using the Password

All sponsorship goes direct to the Charity via your online JustGiving page. At least 50% of the sponsorship target should be with the Charity by 1 week prior to the Challenge. At this time the Charity pays 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 by your charity. The remaining 50%, and any extra, should be with your Charity by 4 weeks after the Challenge.

Most frequent questions and answers

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.

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.


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

No, not for the 2020 Chiltern Challenge.

  • Yes you can sign up others, but not in the same transaction – you will need to go through the registration questions & payment per person.
  • When signing up on behalf of others, please ensure that the YOUR INFORMATION section is always filled with YOUR information as the account holder (regardless of whether you are personally taking part or not).
  • The next section (PARTICIPANT INFO) asks ‘Who is this registration for?’ and you can then select ‘Someone Else’ and proceed with their details.
  • Where possible, please avoid using the same email address for more than one person.

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 to register can then select to join a team, and will be asked to provide these details 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 Flexi-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!).


‘Our Charity Team’ is special registration option and is restricted; if you sign up on this option your team must have at least 4 members, all fundraising same charity (and this must be one of our official Series ‘Partners’).

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. 

Due to the close proximity of the event, we are unable to accept new charities to work with us on this challenge. So we would recommend Self Funding your place, then you will be able to fundraise for a charity of your choice with no specific target.

If you are signed up to the challenge, prior to 24th August and you wish to cancel your place we will be offering a 75% refund on all Self Funding places, CLICK HERE to complete our short form.

This option will be available to you, however please bear with us and check back on the website in a couple of days for an online form to complete this request.
