How tough is it? (walking)

There's no denying it - this is a tough challenge by anyone's standards. It will be physically and emotionally demanding! You will have to combat fatigue and tiring limbs as you battle through the challenge!

You will need to prepare - and should read the training advice issued carefully. The more comfortable you are with walking long distances for sustained periods the more comfortable you will be on the challenge.

You should also practice walking at night at similar times to those projected on the schedule - to get your body accustomed and used to the sensation of working when it's normally sleeping and recovering!

A training plan will be issued in the participant's area of the website to assist in your preparation for the event and we organise regular training walks to get you fitness levels up, as well as to give you the experience you require which will really help you to complete the challenge!

Am I fit enough to Run/Jog?

To run 100km is a double marathon and 50km is a 'marathon plus' distance - across difficult and varied terrain. This is no road marathon and the running category of the challenge is classed for only those who are attempting the 100km challenge within under 15 hours and the 50km in under 8 hours. 

The full support we provide on our challenges for runners means that if you have previously run other marathons and now looking to step up your distance to something longer - this is the perfect event to support your challenge!

If however you would like to run and jog (and perhaps walk too!) some of the challenge then you enter into the challenge as a walker and attempt the challenge in that category.


WIll I need to train?

Ultra Challenges are tough events and training is essential for everyone. Preparation is key and will aid your enjoyment of the challenge whilst ensuring that your body is up to the rigors of the event.

It is very important for all competitors to train properly and build up endurance and resilience thresholds, alongside your base fitness. This will enable you to cope with the distance and provide you with the ability to recover between stages during the challenge.

You will have access to an event specific training guide to aid with your training and preparation, it can be found in the Participant's Area.

If you're looking to run the the challenge, the following links could be valuable resources for your preparation:

Can I change my distance?

If you wish to increase your distance, you will need to send us an email (see Contact Us page) and pay the remaining registration fee. If you are decreasing your distance, let us know by email (including WHICH part of the route form the available options you'd like - e.g. 1st Half) - however we cannot offer a refund on the difference. 

What about food?

Food and drink is fully included in your registration fee! Approximately every 12-13 km there are manned checkpoints and replenishment stops where water, energy drinks, teas, coffee, cake, crisps, and many more energy snacks are provided!

The first major rest-stop is a picnic lunch at ~25km then main hot meals are served by our specialist catering team at ~50km, ~75km, and a celebratory breakfast/lunch/brunch as you cross the finish line!

The event catering will be mixed, varied, delicious and plentiful, with calorific intake a priority.

At the finish there will be a celebratory hot brunch/lunch available to all participants (supporters are charged a nominal fee - bookable in advance).

For runners - there will be an extra supply of energy products available throughout the event.

Am I quick enough to run it?

We ask that you register as a runner if you think you will complete the course in 16 hours. This is so we, the organisers, know how many runners are on an event so can arrange runner provisions and start times - you will not be stopped on the event if you go over this 16 hour mark.

What do I carry?

You are responsible for your personal items on the event and an equipment and clothing list will be available to download from the Participant's Area. Some items are essential/compulsory, others recommended.

You will need a daypack (c30l) to carry the recommended personal items throughout the event including wet weather gear, warm clothing, water, snacks, sun protection, personal first aid kit, and personal items.

At registration you will be issued with a event bib (to be worn on your back/backpack during the challenge), an event pass & lanyard to be worn / carried with you as it will have your timing chip on it.

There will be a baggage transfer service (at an extra charge) from the start to the finish line for a single piece of baggage not exceeding 75l/20kg - this is bookable on event day. Those taking on 100km can also get their baggage taken to halfway, use any items inside, and then onto the finish. Participants who retire from the challenge will be responsible for claiming their baggage at the finish line. 

Registered Runners will have an extra baggage service - where you will be able to access your bags at the half-way mid point on the challenge should you not wish to run with your bags. Half & Quarter Challenge runners will also have a baggage service for free to take a small rucksack (no larger than a 30l backpack) to their finish line.

Among the food we provide, we cater for vegetarians, vegans, gluten-free needs and any other needs. You will be able to indicate any options you may need within the registration form. Additionally, it you do not see anything immediately suitable for you on the Challenge, out catering team are always more than happy to put something together for you. Of course, if you have any favourite snacks then do bring a small supply!

How do we navigate?

You will receive a route map online before the event marked with rest-stops, hazards and distances. The route will also be clearly and fully signed with pink directional arrows and the night time stages will be supplemented with reflective tape and glow sticks - meaning you never have to worry about finding your way and you can just concentrate on the Challenge!

What if I get lost at night?

All stages of the route are fully signed - and during the night stages we use reflective and glow-in-the-dark signage so you will always be able to see the marked route. It is also compulsory that all challengers wear a head-torch during the night sections, and a reflective item to wear which will be provided for you.

The night stages will also be heavily supported by our team of head walkers you will not be on the course by yourself and we encourage groups to join and walk together during the night stages. We will also be tracking every walker at each check point with electronic tagging.

It will be compulsory for you to carry a charged mobile phone and we will have an emergency contact number and contact procedure in the unlikely event you do get lost. Our control room will be on standby throughout the event to help anyone in need.

Where are the route maps?

You can find a provisional route map linked on 'The Challenge' page - finalised route will be published closer to the Challenge. You will also receive a hard copy on the day of your Challenge.

What if I need to retire?

If you unfortunately have to drop out of the challenge, you will need to do so at the nearest check-point if possible, where you will need to alert the event organisers, who will 'log' you out of the event. 

From the half way stage onward there will be support vehicles, and shuttle services to the nearest train stations for you to safely and easily return home.

Can I bring my dog with me?

No - unfortunately we do not allow dogs to take part in the challenge as we cannot cater for them along the route and can be difficult to manage on the challenge. We do however think dogs make for great training companions.

How do I get to / from it?

The Participant's Area is full information about transport links at the start and finish and approximate start times will be published. Further details will be released as we draw nearer to the Challenge.

What shoes should I wear?

This very much depends on how you are taking on the challenge - if a runner then we recommend the shoes you usually train and run in.

Walkers we recommend that you wear the shoes or boots you have been training in - so your feet are as comfortable as possible on the challenge - some people choose to wear sturdy trainers, whilst other opt for ankle height walking boots to give maximum support to your ankles and feet. It is a personal preference and we recommend that you experiment when going for training walks to ensure on the day you will be as comfortable as possible.

2019 Divider 699


How can we join as a team?

All teams entering need to be set up by a 'team captain' - this is the first team member who signs up to the Challenge and creates the team and gives the team a password. Then the additional team members can sign up via the website by selecting the "join an Existing Team" option on the registraiton form. They will then be able to select the team by searching for it. The form will ask them for the team password (which they should have been given by the team captain).

There is no limit to the number of participants you can have in a team - however we recommend that everyone is of the same fitness level and pace.

Being in a team will guaratee that you all get the start start time (if starting from the same point).

Can we pool our fundraising?

The Fundraising targets are per person, not per team. If fundraisisng forthe same charity, you can all fundraise together on one page. However you must reach the SUM of everyone's fundraising targets and the charity must know the names of everyone the page is attributed to. 

Can I meet other walkers?

Once you have signed up to the challenge you will be invited to join our Facebook page where you can find your event's page, whereby we encourage individuals and teams of people to meet, converse and organise training walks. It is a great way to connect with other individuals on the challenge and there is always a discussion going on! If you then want to you can arrange to start with the people you have met prior to the challenge.

Different charities in a team?

Yes, this fine. However, you will need separate Just Giving pages and will each need your reach your fundraising minimum target.

2019 Divider 699


How do I start fundraising?

Once you have signed up to the Challenge and received contact from your chosen charity, you can set up your online fundraising page by logging on to Just Giving Once you have set this up you can start sending out the online link to all your friends and family to start collecting donations!

Your charity will also send you a welcome pack which will give you advice and support on how to go about your fundraising plans.

What if I miss the target?

Ultra Challenges are events for charity - and therefore by signing up you are committing to fund raise the minimum sponsorship for your chosen charity - with 50% of that fundraising total due in to your charity 6 weeks prior to the Challenge  - See Challenge timeline in the Participant's Area. 

Failure to meet the initial target could result in you being unable to take part in the challenge. However this is down to the discretion of the charity and will be decided on a case by case basis. If you are cancelled from the Challenge, you will be given the opportunity to pay your own costs on the Challenge (become a self funder). The event is tough - but in may respects that makes it a bit easier to find willing sponsors, as it is no ordinary charity challenge. In 2016 the average fundraising total reached by our challengers was over £1,000- often once you get the ball rolling you will see the collections and sponsorship flood in!

I don't have a charity pack

Once you have signed up to the challenge your charity is likely to send out a fundraising pack - if you still haven't received this please contact your charity within 2 weeks of signing up to the Challenge. Note that Action Challenge do not send anything out by post.

My charity's not on the list?

If you wish to fundraise for a charity not listed, you can still sign up to the challenge by letting us know who it is at the charity you would like to fundraise for, and we will contact that charity to see if they will welcome you onto the challenge. We do however ask that you do not start fundraising until you hear from us that your charity has accepted you as a fundraiser - and if we do not hear back from them within 2 weeks we will contact you to advise you select another charity or self fund (see How to Join page for details). 

Can we pool fundraising?

Yes - as long as you are all fundraising for the same charity - you can create a team fundraising page on Just Giving - we also recommend that you let your charity know this is how you will be fundraising. You will still have to reach the combined total amount as the target is per person, not per team.

Fundraise for 2 charities?

No - you must one select one primary charity for whom all your fundraising will be in aid of - this is because your charity will pay for a portion of your place on the event, out of the fundraising generated. If you still wish to fundraise further for another charity, you can do so on your own terms as long as you reach the minimum target for the first charity.
