What an event 2026 was 🤩 The highest highs and lowest lows felt by everyone involved. This is what makes the BYU an absolutely unmissable experience.

We asked Dave Wood to share his favourite moment from this year's Suffolk Backyard Ultra Festival. These are his top 4:

1 – I love when the event goes into its first night, the atmosphere changes. The sight of the head torches moving together, the sound of everyone’s feet pounding the gravel in the first dark mile. There’s an energy in that moment which gives a renewed sense of a unified goal for everyone on the course.

As a photographer, working with limited light means I have to look at everything differently, more creatively. The challenge evolves for me, as well as the athletes.

2 – Passing the 24hr marker is really exciting. Many will drop out because they’ve reached 24hrs or 100 miles, never knowing just how far they really could have gone. Now, the “big dogs” are barking!

I love storytelling from behind the lens. After a day with them all; personalities begin to show. Even quiet personalities can stand out. You begin to notice new friendships forming, though occasionally, they’re quickly dashed by an unexpected DNF. Athletes closing in on a qualification status for their national team and age-specific records are now within sight and the positive energy to see them reach further becomes palpable around the event village.

3 – What makes these events inspiring are the moments when the tiredness, emotions, pain and relief shows. Spreadsheet plans are the last thing on anyone’s mind when their feet blister, knees weaken and the strength of resolve is challenged in a sleep deprived mind.

The format is a celebration of failure by its very nature, even the eventual winner can falter along the way.

4 – The top moment had to be on the final lap. Dave Phillips sensed he was now the lone athlete on the course. I found him at around 2.5miles in, travelling at speed and keen to finish in style. I texted our event WhatsApp group “he's flying around”, in the hope that everyone would be ready for this impressive final lap.

I realised the problem I now had was to make it back to the finish line quicker than him! Luckily, I had learned the mazy network of forest paths well and found a way to get back, camera gear in hand, to join everyone else at the finish line to welcome him back.

What was your favourite moment?

64 Yards - 266.6 miles - Sam Mayhew
The Assist.

From the very beginning of the backyard, Sam was cool and calculated. Having ran 35 yards at a capped event previously, Sam was ready to test himself.

He drifted seamlessly through the opening 24 yards with seemingly no effort. In fact it was so seamless because as soon as Sam crossed the line, he was back in his tent with his crew in seconds. It was like clockwork because it was designed to be so.

Now....Sam's crew. Wow.

- They'd secured the closest spot to the start line
- The tent was huge, immaculate, a home away from home
- The nutrition, measured, considered, varied. Always a plan B, a plan C, probably a plan D.
- They quietly watched the competition for any nugget of information to raise Sam's spirits.
- They rotated a person sleeping so someone was always awake and fresh to help.

True friendship made the difference here. They were not going to let their man quit and Sam believed it too. You could see it on his face, he was going to reach his goal.

As tenacious as he is talented, it's blindingly obvious how strong a runner Sam is and he will go far.

This is just the beginning.
Get in Sam.

65 Yards - 270.8miles - Dave Phillips 🏆

A newcomer to the backyard format, Dave was curious about how he would fare. Dave is no stranger to long distances. With a whole host of FKTs to his name, both supported and unsupported, not to mention multiple high level race podiums, Dave knows how to manage himself on everything that tests you in a backyard:

- Sleep deprivation
- Fuelling
- Fatigue
- Mind games

With a very measured approach, he quietly moved about the course, never giving too much away, taking notes of the process. One thing that was becoming clear, he wasn't going to quit.

After the field whittled itself down, Dave's experience shone and to the benefit of all who remained. His cool calm demeanour revealing a passion for wanting to help others succeed. Forever encouraging the younger runners, it was clear he was more focused on helping them achieve their dreams than his own.

How far Dave could have gone, we'll never know, but he certainly got a glimpse of his unyielding potential, will we ever see him reach it?

Congratulations Dave, what an inspiration.

Sam and Dave are out on the 64th yard.

One more yard till daylight pushes its way between the trees to light the forest on the 4th day and almost 267 miles.

Will we reach 72 hours and 300 miles at 12pm today, will we continue on to towards 96 hours and 400 miles tomorrow?

They currently look strong and are consistent at around 51mins per lap.

60 yards - 250 miles and still going.

Spirits are high with these two, they bounced off into the dark and returned happily. Still very consistent with lap times, running form intact.

Both are managing sleep each lap, both have crews helping reduce all faffing to a minimum.

Everything is working.
4 hours till daylight.
Keep going guys.
You're amazing.

Unfortunately there has been a rule breach and George Rickwood has been disqualified as a result. We received footage that meant the following rule had been breached:

Rule 3 - specific rules

"No handing over of kit, ditching kit or support of any kind from the start whistle until the end of the loop"

Rules have to be followed, otherwise the integrity of the event is nullified.

Juan Diego Aguilar Bravo has DNF’d after 51 laps.

His goal had been to break 48 laps to qualify for the Spanish team. He carried forward, past 48, fueled by the energy of his crew and the spectators who refused to let him stop short of what they knew he could achieve. By the time he crossed 51, he hadn’t just met the standard, he had secured his place in the team with authority.

On his final lap, he ran the entire loop holding a photograph of his late father.A quiet tribute to accompany him every step towards a dream now realised.

When he returned to the finish line for the last time, he was met with a wave of applause and warmth, especially from his fellow Spanish runners who had stayed on to support him. It was a finish that felt less like a DNF and more like a homecoming.

Congratulations on your qualification to the National Team Juan and thank you for the atmosphere that you all brought to our event this year. Please come back again.

An emotional moment on the course today. After 45 laps, Tom Monro stepped out for lap 46, with the vocal support of his crew, the spectators and the four remaining athletes.

Even with the strong encouraging arm of Dave Phillips beside him, Tom eventually ground to a halt, made his way back to the start and called his DNF. There were tears. There were hugs. There was the kind of exhaustion which carries a huge sense of pride.

There are very few people who can say they've run 187.5 miles but very, very few can say they've done it at just,
19 years old.

Thomas, that was special. Thank you.
