Five days. Nearly 500 miles. Two runners pushing the limits of human endurance.
I’ve been following the 2026 Big’s Backyard Ultra World Team Championship since Saturday, and what I’ve witnessed has been extraordinary.

As the competition progressed, countries began dropping out one by and now only Belgium remains.
Ivo Steyaert and Merijn Geerts continued answering the starting bell every hour, pushing beyond the previous world record of 119 laps.
To appreciate that accomplishment, consider what 120 laps represents: nearly 500 miles of running, five consecutive days of hourly starts, and multiple nights with very little sleep. All the while, these runners had to keep finding a reason to continue.
And somehow, they kept going.
What Happens When the Finish Line Keeps Moving?
Most endurance races have a defined endpoint. A marathon ends at 26.2 miles. A 100-mile ultramarathon ends at 100 miles.
A backyard ultra is different. Every hour, runners must complete a 4.167-mile loop. Whatever time remains becomes their opportunity to eat, recover, and prepare for the next start.
There is no predetermined finish line.
The physical demands are enormous, but what fascinates me most is the mental challenge. How do you keep moving when you’re exhausted, sleep-deprived, and uncertain when the race will end?
The Science of Extreme Endurance
After five days, these athletes are facing challenges that go far beyond ordinary muscle fatigue.
Sleep deprivation can impair attention, decision-making, and emotional regulation. Repeated muscular loading increases tissue stress, while maintaining adequate nutrition and hydration becomes increasingly difficult.
Yet these runners continue performing at a level most people would find difficult even when well-rested.
I find this balance fascinating. Endurance isn’t simply about ignoring fatigue. It’s about managing physical and mental resources for as long as possible.
Pacing, preparation, nutrition, recovery, and psychological strategies all play a role in how far an athlete can go.
Two Runners, One Extraordinary Achievement
Perhaps the most compelling part of Belgium’s performance is the role the final runners play in pushing each other forward.
In a backyard ultra, the last two competitors can help each other reach distances they might never achieve alone. One runner’s willingness to continue gives the other a reason to attempt another loop.
There is a lesson here that extends beyond running.
We often celebrate individual accomplishments while overlooking the people who help make them possible.
Whether we’re training for a race, recovering from an injury, or trying to improve our health, having someone who encourages us to keep going can make a meaningful difference.
Sometimes our greatest contribution isn’t achieving something ourselves. It’s helping someone else discover what they’re capable of. I have read in the comments that they had a strong friendship prior to start of this race too, which could be another discussion.
The Bigger Lesson
Most of us will never attempt a 500-mile ultramarathon, nor should we need to.
But watching these athletes has reinforced something I believe applies to everyone. Our capabilities can exceed what we initially imagine, especially when we approach difficult goals with patience, preparation, and support.
That doesn’t mean ignoring warning signs or pushing beyond safe limits. Extreme ultramarathons carry significant risks, and these performances shouldn’t be treated as a model for everyday exercise.
Instead, we can take inspiration from the principles behind them. Break overwhelming challenges into manageable pieces. Build sustainable habits. Prioritize recovery. Surround yourself with people who support your goals.
When progress feels slow, remember that meaningful accomplishments are often built one small step at a time.
Sometimes the most remarkable thing about human endurance isn’t how far someone can go. It’s what becomes possible when people help each other keep going.
Keep moving forward.
