To all 2020 Chiltern Challengers

We’d like to congratulate everyone who took part in the 2020 Chiltern 50 Challenge – the first ‘non-virtual’ event for many months!

1,100 set out from the Henley base-camp, and everyone did incredibly well – with 96% completing their distance. We were pleased to see so many familiar faces and to have been able to provide support throughout.

We would also like to say a huge thanks, as the array of Covid risk reduction measures were followed impeccably – and we are pleased to confirm that it was described as a ‘model event’ by the Council officials who visited us on Saturday.

Overall it was a fantastic day and a great showcase for how events like these can operate in 2021 – which will contribute to the well being of all who take part, and hopefully support many of the charities that have seen a complete fall off in fundraising. We hope that all our past & future participants are feeling assured as to how our Ultra Challenges will be run safely & responsibly, and that you will be joining us once again in 2021.

Event Format Changes

In order to get the ‘green light’ from the councils & authorities, we’ve had to adapt our model and introduce a range of measures to ensure our event is deemed deemed ‘Covid Secure’ – which has lead to a number of changes to the originally planned event. Take a look so that you are aware before signing up.

If you were already signed up to the Chiltern Challenge and wish to defer your place to a 2021 challenge, or to cancel your place, please complete the short form on our ‘Sign Up’ page.

The 50 km route will now be 2 loops of 25 km – an ‘east’ & ‘west’ – meaning that all focus will be on the one hub location in Henley, and removes the requirement for us to have two ‘hub’ venues in the local community, and complex transport set-ups – as we have plenty of parking available.

The 25 km route option will now be the ‘west’ loop – starting and finishing in Henley.

There will be rolling staggered starts to minimise bunching.

One of the provisions we’ve agree to with the council was to not allow general camping on the Henley site, to reduce the number of participants on-site at any time. Therefore we now recommend using local campsites, or accommodation. 

We’ve also agreed that we will not host a bar on site, or to allow for any form of prolonged  ‘celebration’ or ‘gathering’ in the way we had originally planned – as we need to manage & control footfall through the site.

If you’re planning on having supporters join you, please be aware that they will not be allowed into the ‘central marquee hub’ of our main site in Henley. Instead, e will have limited seating & cover for supporters off to one side, which will be controlled. We will also not be able to cater for supporters, so they will need to ‘self sufficient’. Again – these measures are designed to enable us to control the total number of people on-site at any point in time.

Our medical resource is going to be focusing on first aid, and emergencies. Due to the close contact nature of massage we have agreed that we will not provide this service at the event.

We will be posting out to your home address your bib & timing chip, to minimise the ‘contact’ and congestion at registration with our staff. 

We are unable to accommodate Friday night camping, dinner or pre-registration. Access to the site in Henley will be open from 6.0am on Saturday morning – and strictly on the basis of a maximum of 45 minutes before your allocated start slot.

Alongside the above event changes, we will also be implementing standardised measures to keep all participants safe whilst on the challenge. You’ll see special social distancing requirements & hygiene measures in place across many elements of the events, ensuring each Ultra Challenge is as low risk as possible for everyone involved.
