Yes — a backyard ultra is scheduled for the weekend of July 18, 2026, but "the" race is not a single event. The most clearly documented one is the Ode to Laz Michigan Backyard Ultra in Holly, Michigan, starting Saturday, July 18 at 9:00 a.m., according to its UltraSignup registration page. A backyard ultra is a last-runner-standing race: everyone runs the same short loop every hour until only one person can still complete it. Below is what the format demands, what the July 18 event involves, and how to confirm which race an article actually means.

What "backyard ultra" means
A backyard ultra runs on a fixed rhythm, not a fixed distance. runners complete a 4.167-mile (6.706 km) loop every hour, on the hour, as described in the Wikipedia entry on the format. Finish the loop before the hour ends, and you rest until the next start; miss the cutoff or a start signal, and you are out.
The math is deliberate. Twenty-four loops equal almost exactly 100 miles in 24 hours. The race keeps going hour after hour until only one runner completes a loop alone. That final runner is the sole official finisher. Everyone else records a DNF ("did not finish"), and the last person eliminated is credited as the "assist." This is why total distance is unknown until the race ends.
The July 18, 2026 event in Michigan
The Ode to Laz Michigan Backyard Ultra takes place in Holly, Michigan, starting Saturday, July 18 at 9:00 a.m., per its UltraSignup listing. The name honors Gary "Lazarus Lake" Cantrell, who created the backyard format. The course changes character with the clock. By day, runners take a 4.167-mile trail loop with about 350 feet of gain over mostly technical singletrack.
From 9:00 p.m. to 9:00 a.m., the race switches to a paved, closed park road with roughly 250 feet of gain per loop. The rules hold to the standard format. No outside or crew assistance is allowed on the loop itself, and each lap must finish inside the hour with the runner back in the starting corral, ready for the next start.
Why this race carries extra stakes
The 2026 Ode to Laz is a "Silver Ticket" race. Its winner can earn a spot on the USA national backyard ultra team, according to the event registration details. That eligibility is limited to U.S.
residents. This raises the competitive ceiling beyond a typical local ultra. Runners chasing a team spot may push far longer than someone aiming only to finish, which can stretch the event well past a full day.
How far do backyard ultras actually go?
Elite backyard totals can be staggering, but they are the exception. At the October 2025 Big's Backyard Ultra world championship in Bell Buckle, Tennessee, Phil Gore won with 114 loops — about 475 miles, as recorded in the Wikipedia entry on Big's Backyard Ultra.
Most runners finish far fewer loops. The format guarantees only one official finisher, so the vast majority of a field records a DNF no matter how well they run. Treat those world-championship numbers as a ceiling, not a benchmark for your own first attempt.
Make sure you have the right race
Several backyard ultras fall on the July 18, 2026 weekend across the country. A weekend listing from Ultra Running Magazine shows multiple events, so "the" July 18 backyard ultra is not singular. Before you register, travel, or share an event, confirm the specifics: For the Michigan event specifically, the Ode to Laz UltraSignup page is the source to verify against.
- Match the exact race name and host town, not just the date.
- Check the start time and time zone against the official page.
- Confirm the loop surface and whether it changes overnight.
- Verify eligibility rules, such as the U.S.-residents-only "Silver Ticket" condition.
- Re-check the registration link directly, since fields and dates can change.
Frequently Asked Questions
What happens if I miss one hourly start?
You are out. Every runner must begin each loop at the top of the hour and finish it before the next start, or the race ends for them.
How long does a backyard ultra last?
There is no set end time. It continues loop after loop until only one runner completes a lap alone, so it can run well beyond 24 hours.
