team

Support crew

One or two people (ideally two)

Role

Support crews meet their team at each checkpoint along the route. They carry extra kit (ie. wet weather gear and warm clothing), provide additional food, replenish water supplies, and most of all, motivate and encourage their team. It will be an epic adventure and a big achievement for the crew too, as they support you physically and emotionally for the full 100km.

Vehicle

The vehicle must be no larger than a 12-seater minibus (2.5m × 5.5m). You’ll need enough space for the whole team (in case of drop-outs) as well as for the support crew and equipment.

Fitness level

A 100km walk is achievable for most people, but you will need to dedicate time to train, especially as a team. Most teams will plan long weekend walks alongside some shorter evening sessions plus you will receive a Trailwalker training guide.

The Relay

Introducing the brand new Trailwalker Relay! Divide and conquer the 100km route across the South Downs between a team of 6-12 participants.

Trailwalker stands apart from all other endurance races as a team trial – camaraderie and resilience are the beating heart of the event. The Trailwalker Relay fosters that team spirit, breaking the breathtaking 100km route across the South Downs into four sections. Teams of between 6 and 12 participants can join forces to conquer the historic challenge.

Highlights

  • Assemble

    Relay teams must have a minimum of 6 and maximum of 12 participants, plus 2 support crew. Nominate your team captain.

  • Register

    Complete the team registration and pay the registration fees. Individual participants and support crew must then complete their personal registrations.

  • Strategise

    Decide how you will divide the distance. Participants can swap in/out at Checkpoints 3, 5, and 8. There must always be at least 3 team members on the course.

  • Train

    How much of the route you intend to complete and your preferred pace will determine how much training you need to do.

  • Fundraise

    Each team member is encouraged to set a fundraising target of £300, but your whole team is responsible for reaching your collective fundraising goal.

  • Prepare

    Ensure all personal details are up to date via your registration dashboard, and everyone has the essential kit ahead of the event weekend!

Tips from participants

Train as much as you can – on your own, with your team or with friends. Even if you are already fit and active, you need to get used to the time on your feet. I highly recommend getting a good pair of walking poles – helps keep you steady on the rough trail and a godsend when you’re tackling the big hills. Remember to take lots of photos – it’s an experience you’ll never forget!

Heather Hitchins, Trailwalker 2022 - GWT Platinum Jubilee Team

Have good walking/trail running shoes and if you’re getting new ones, make sure you break into them well before the event. Train on the routes where you will most likely be walking through the night, so you’re familiar with the path. Have good communication with the rest of your team and your support crew before and throughout the walk. Checklists for each checkpoint helps a lot, so your support crew know what you expect.

Anju Gurung, Trailwalker 2019 – Team Spitfire

Set a realistic target – to get the whole team to the finish in under 30 hours is a massive achievement. Anything quicker is a bonus! Work out a plan based on the time to complete each stage, at a steady pace that everyone is comfortable with, and don’t forget to include rest time at checkpoints. Expect to slow down after 50km and remember the weather may play an important part.

Chris Green, Veteran of 8 Trailwalkers 2015 to 2023 – The Pukka Burhos

Choose your team, initiate your fundraising, and start your training early. Build your training up slowly and steadily, and make sure you train with your support team at least twice before the event!

Piers Lawson, Trailwalker 2019 – Team 24 Hour Dal Bhat Power & Trailwalker 2022 – GWT Platinum Jubilee Team

We are all married to current or ex-Gurkha officers. We really understand the important work that GWT does in Nepal and are all passionate about supporting you. It’s been a pleasure to fundraise, and hope we can nudge our total up a bit further before the weekend!

The Gurkha Welfare Trust

GWT

About the charity

The team of dedicated staff journey into the hills of Nepal to deliver essential financial and medical aid to the most vulnerable pensioners. They also work with local communities to provide access to clean water and education.

Fundraising support

An online fundraising page will automatically be created at the point of registration, and we will provide lots of hints and tips along the way to help you reach your goal.

Fundraising ideas

  • Cook up a storm

    You don’t have to wait until the Trailwalker finish line to enjoy a Gurkha curry! Host a Nepali curry night, and ask for donations in exchange for a ticket to your exclusive supper club.

  • Become the Quizmaster

    Invite your friends, family, and colleagues to a local pub or community centre for a quiz night. Test their general knowledge, and include a special Nepali-themed round for double points!

  • Flex your sales patter

    Sell your unwanted items via an online platform or at a car boot sale, and de-clutter your home at the same time! Nothing to spare? Ask local businesses to donate items for a raffle or auction.

The difference your sponsorship makes

  • £300

    could fund 1000 metres of pipeline needed to bring clean water to a community, improving sanitation.

  • £1200

    could provide a pension for one year, a lifeline for many vulnerable Gurkha veterans and their widows.

  • £200K

    could pay to build a school, complete with classrooms, a library, and toilets. The aim is to complete two projects of this scale every year.

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
