Without the EAAA crew that day, Steve would not have met our two youngest grandchildren. We are both now EAAA volunteers. It is our way of giving a little something back to the charity that gave everything back to us. We hope that the people of Bedfordshire will get behind East Anglian Air Ambulance’s Trek 24 this April to support this life-saving charity.

For our Bedfordshire treks, the route is circular so your meeting point will be both your start and finish line! Specific timings and locations will be communicated to you via email.
The minimum age for taking part is 17 years old on the day of the event.
All participants MUST bring their own reusable water bottle. There will be opportunities to refill it at various points along the route. You may wish to wear a hydration/camel pack however, this is not essential.
Toilets will be provided at the start line, the finish line and at rest stops. There may also be additional public toilets open and available to use along the route.
Unfortunately, we are unable to accommodate dogs at this event due to the routes passing through land where there may be livestock present or wildlife protections in place. If you have a guide dog and would like to take part in Trek 24, please get in touch with our events team on info@eaaa.org.uk.
If you become tired or injured and feel that you may be unable to complete the course in time, our course marshals may be able to provide a ‘boost’ along the route to ensure you are able to complete the event. We highly encourage following a training plan for this event to ensure you are physically prepared for the challenge. If you need to drop out at any point of the event, please ensure you make contact with our events team, contact information will be provided on the day.
Unfortunately we don’t have an accessible route for Bedfordshire, however there is a fully accessible 2.4 mile route on the Norfolk Trek.
Yes! This will be provided in the information pack sent to you and you can also find it here.
Your registration fee alone is not enough to cover your full event costs including your refreshments, toilet provision, medical support, coach travel and insurance. East Anglian Air Ambulance depends on the participants of Trek 24 reaching their minimum fundraising target in order to raise the vital funds needed to keep our helicopters flying. If you are concerned about being able to commit to a fundraising target, please take a look at Ticket Option 2, whereby you can pay more for your ticket, and fundraise as much as you can.
Trek 24 is organised by East Anglian Air Ambulance and is run by the Charity’s own staff and volunteers. Therefore, we ask that any participant taking part in this event raises sponsorship exclusively for East Anglian Air Ambulance.
Lunch will be provided to eat whilst on route. A hot meal will also be provided at the finish line. We would also suggest that you may wish to bring your own additional snacks if you are likely to feel hungry during the day.
