We love reading your reviews because your experience is what it’s all about.

The Suffolk Backyard Ultra Festival is considered the UK’s oldest established Backyard Ultra. And you know what they say… the original is always the best.

First held in 2018, we’ve been growing and evolving while staying true to the core principles.

Fancy joining us on 6 June to test your limits?

** Challenge Running Needs You **

National Volunteer Day is 5th December 2026, but we need you now!

People volunteer to make a difference in their communities, support causes they care about and gain personal fulfilment. Key motivations include meeting new people, learning skills, enhancing career prospects, boosting mental health (reducing stress/increasing confidence) and finding a sense of purpose.

Others just do it for the points against future events :D

Be that person in 2026 - volunteer!

We are always on the hunt for support for all of our events but in particular we have an urgent need for extra support for the Thames Ring Series which starts on 22nd April, the Suffolk Back Yard Ultra Festival starting on 6th June and on 11th July, the Thetford 24 Hour event.

You can find out about our volunteering opportunities, how our points system works and offer your support by visiting our website, www.challenge-running.com/contents/3109-volunteers.

We'd love to get more clubs involved in volunteering at our events; we will give whoever volunteers at the event the usual points but also for each checkpoint location staffed by a club we will donate a few places for that years event for the club to use or to raffle off, or give to runners they choose.

Some call the bell cruel. We think it gives closure. After all, there can only be one winner at the Suffolk Backyard Ultra. Everyone else earns a DNF... and a dog tag.

Come and test your endurance, your resilience, your grit and your determination with us on the 6th June.

Shut off from the rest of the world and see how long you can put off ringing that bell!

Last month Lazarus Lake shared a reminder that backyard races are growing fast, and only affiliated events count for rankings, recognition, and championship pathways. Some events are not following the official rules, which means results cannot be recognised after the fact.

If you enter a challenge running a backyard ultra with us, you do not need to worry. We are an affiliate, all results count, and your performance puts you on the path towards national teams and the championship.

6th June - Suffolk Backyard Ultra
12th September - Thetford Backyard Ultra

Big Dog's Satellite Championships: Team United Kingdom held in October!

Hi all. Volunteer call out.

We have had one of our van drivers drop out of the Thames Ring events starting on Wednesday the 22nd of April. If anyone is available to drive a baggage van from wednesday to Sunday morning that would be much appreciated.

We pay the hire on the van and all fuel etc. you just move bags around between checkpoints on a pre planned schedule and maybe help out on the odd CP if it's busy. Plenty of time for rest/sleeps in the van.

If you have your own van we will pay you what we normally pay for the hire for it's use.

If you can email us on lindley@challenge-running.com or go to the volunteering page on the website https://www.challenge-running.com/contents/3109-volunteers and full in the volunteer form.

We also need a few more volunteers at the checkpoints so if you are free please also fill in the volunteer form.

Really feeling for Eric and the whole Rasselbock Running team after having no choice but to cancel the Backyard Ultra due to dangerously high winds.

There is nothing harder for a Race Director than having to stop a race, especially when so much work has gone into it and such a strong field had gathered.

It sounded like it was shaping up to be something special, with what may have been a record number of runners reaching the 35th loop. That says a lot about the quality of the field and the spirit of everyone out there. Huge respect to all the runners who took part and handled the conditions.

We know Rasselbock will be back in September at Hardwick Hall for another great event and we are sure the community will get behind it again!

Volunteers make the magic happen.

Behind every finish line smile every quiet word of encouragement and every runner pushing past what they thought was possible there is a small army of people giving their time to make it happen.

Join us at Suffolk Backyard Ultra or Thetford 24 and be part of something special. Experience the buzz of race day from the inside. Cheer runners through the night. Help someone dig deep for one more lap. Share laughs stories and hot drinks with a welcoming trail running community.

It is fun inspiring and genuinely rewarding.

We also like to say thank you. Earn volunteer points for every hour you help with free race places discounts and sometimes race merchandise. Volunteer now and run later or build points across multiple events. It is flexible fair and designed to give something back to the people who support our runners.

Whether you are marshalling helping at HQ or simply offering encouragement when it is needed most you will be helping someone reach their goal their comeback or their personal best.

Come for the atmosphere.
Stay for the community.
Help make it happen.

We would love to have you on the team.
