On October 21, 2023, a small, invitation-only crew of athletes will run 4.167 miles in one hour. Then the runners will do this once more each and every hour, for so long as they are able to. Welcome to Giant Canine’s Yard Extremely, and the arena of yard ultrarunning.
Because the yard race layout differs from maximum different operating races and it’s relatively new, we use this newsletter to provide an explanation for the origins, logistics, and enchantment of yard races. As you’d be expecting from this column, we draw on quantitative information to tell our dialogue of the development’s recognition and runner efficiency.

Method
The tips for this newsletter comes essentially from an interview with yard race author Gary Cantrell, and a dataset created for the Yard Extremely site to trace more than a few occasions the usage of the yard layout and performing as qualifiers for Giant Canine’s Yard Extremely, which acts because the Yard Extremely Global Championships. (Qualification for this maximum prestigious yard extremely is completed via profitable some of the more than a few nationwide championships, or via reaching a top place at the layout’s global scores. We can get again to this later.)
We supplemented that dataset with more moderen race effects, and effects for more recent occasions, the place lets download the ones effects from both the DUV Extremely Marathon Statistics site or UltraSignup. The dataset that used to be thus compiled will have to now not be regarded as a complete listing of all yard extremely effects, however you must name it an excessively extensive pattern set.
It Began with Giant Canine
Gary Cantrell, often referred to as “Lazarus Lake,” held the first-ever yard extremely in 2011. He and Sandra Cantrell hosted it within the yard in their farm in Bell Buckle, Tennessee. The direction used to be 4.167 miles, that means {that a} runner who finished 24 loops would duvet 100 miles in that point. Runners entire the 4.167-mile loop on somewhat flat trails all over the day, then on a gravel highway whilst the solar is down.
To be able to stay within the race, runners wish to run 4.167 miles and be at the beginning line for some other loop on the best of the following hour. Runners are given a DNF in the event that they fail to finish a loop on time, or refuse to start the following loop on agenda. Most effective the overall runner status is regarded as a finisher of the development.
As a result of many members run every loop in beneath one hour, they are able to use the time between completing a loop and starting their subsequent loop to eat energy, alternate clothes or equipment, take a rest room wreck, or get a couple of mins’ sleep. And since many members are motivated to run for so long as conceivable to set a brand new non-public absolute best and/or be the final particular person nonetheless operating, good fortune calls for a specific mixture of health, toughness, logistical preparedness, and technique.

Explosion in Recognition
In keeping with Cantrell, different races followed the yard layout inside of months of the inaugural version of Giant Canine’s Yard Extremely in 2011. He estimated the selection of parallel occasions has more or less doubled yearly. As of 2023, he experiences there are more or less 400 races in 78 nations which are affiliated with Giant Canine’s Yard Extremely. There’s no value to race organizers or members to associate a race, so it’s commonplace for race administrators to publish their occasions and effects to the Yard Extremely site. “UltraRunning” mag recorded effects for 73 yard ultras in North The usa in 2022, and 63 for the 12 months thus far, on the time of writing.

Of word, “UltraRunning” mag had additionally integrated one small match from 2010, however as little data might be discovered in this match and Cantrell didn’t officially determine the layout till 2011, we’ve now not integrated it. (Supply: “UltraRunning” mag)
Cantrell credit the recognition of the race layout to a couple of causes:
- It’s relatively simple to host a yard race, in comparison to different ultramarathons. The timing machine may also be so simple as an eye fixed and a work of paper. They just require one help station. It’s considerably more uncomplicated to procure permission for the usage of a 4.167-mile phase of path than, for instance, a point-to-point race masking 100 miles.
- The occasions foster extra camaraderie and socializing than point-to-point races, for the reason that members and crews spend extra time in combination. Even amongst runners with aggressive aspirations, they have got a vested pastime in seeing their fellow runners do properly for a minimum of the 1st 24 hours, so they are able to draw energy from every different within the early miles.
- The development embraces individuals who don’t run ultramarathons. Cantrell shared the tale of a runner who proudly ran for 2 hours (two “yards,” within the parlance of the development), environment a private absolute best. He highlighted how the layout permits runners to run no matter distance fits them absolute best, whether or not that may be a new non-public absolute best, or just an stress-free and well-paced coaching run in preparation for a purpose match.
- The layout forces sensible pacing on someone intending to run 100 miles inside of 24 hours. For lots of skilled ultrarunners, going 24 yards at a yard extremely provides them a brand new non-public absolute best time for the 100-mile distance.
Hobby in Giant Canine’s Yard Extremely has grown such a lot {that a} qualification machine now governs which runners get invited to the development. The entrants’ checklist for the 2023 match consists of winners from nationwide championships occasions and best runners from an at-large checklist at the Yard Extremely site. Since 2020, there was a Global Group Championships in yard ultrarunning, going on each and every different 12 months. Each and every collaborating country can collect a roster of as much as 15 athletes, all of whom are scoring participants. They run in a yard match of their respective nation. Participants of every crew paintings in combination to stay their crew in rivalry for as many yards or hours as conceivable. As soon as a crew is right down to a unmarried runner, that runner has gained the person nationwide championships for his or her nation. The following Global Group Championships is scheduled for October 19, 2024.

Yard Racing Technique
“It’s actually like a distinct operating recreation,” Cantrell says of yard ultras. Runners don’t aspire to be the quickest over a given distance. Fairly, they problem themselves to look for the way lengthy they are able to stay going. Cantrell is fast to indicate girls, masters, and grandmasters runners are all well-represented amongst yard match general winners. He argues that as a result of natural pace provides fewer benefits in yard ultras, the layout rewards the runners who excel at troubleshooting and refuse to surrender.
Cantrell suggests that point control between loops is very essential. “You wish to have to be actually environment friendly,” he says, noting the most productive performers have unswerving crews that paintings properly in combination to organize their runners for the following lap.
The use of the 2019 Yard Global Championships, held at Giant Canine’s Yard Extremely, for example, the Yard Extremely site revealed information on every player’s quickest, slowest, and reasonable occasions to run the 4.167-mile loop. Curiously, eventual race winner Maggie Guterl didn’t have the quickest lap, the slowest lap, or the quickest reasonable of any player that 12 months. Guterl’s tempo left her with, on reasonable, reasonably greater than 9 mins consistent with loop to leisure, refuel, and get ready for the following loop.

Yard Racing Most sensible Performances
It’s commonplace for path operating and ultramarathon data to face for years. As an example, Patrick Reagan’s 2017 direction listing on the Javelina 100 Mile stood till 2022, when Dakota Jones completed some 3 mins beneath it. Ellie Greenwood set the direction listing on the Western States 100 in 2012, and her mark remained unbeatable till Courtney Dauwalter and Katie Schide ran quicker on the race’s 2023 version. Matt Wood worker held the direction listing on the Pikes Top Ascent for 30 years till Remi Bonnet bettered it in September, 2023.
In opposition to that backdrop, data within the area of interest of yard ultrarunning hurtle ahead via leaps and limits. Because the 2019-2020 season (the Yard Extremely site teams performances via a length operating from August 16 of 1 12 months to August 15 of the next 12 months), the once a year listing for many yards coated in a yard extremely has larger via a large margin. The development has noticed a brand new global listing yearly since John Stocker ran for 81 hours in June 2021.

It’s now not solely the record-setters who’re breaking new flooring, both. Because the Yard Extremely site’s global rating checklist displays, there are extra runners operating past 24 hours on this race layout yearly.

Extra runners are operating farther, and a few are operating for greater than 100 hours on this race layout. However that doesn’t imply it’s simple. The yard extremely is deceptively easy — it calls for operating at a tempo that the majority ultrarunners would believe manageable, however doing it for goodbye that runners and their crews will have to be totally dialed in with how they set up fueling, fatigue, and the myriad problems runners stumble upon all over an extremely. The development is “extra psychological than bodily,” Cantrell says.
The Yard Extremely site integrated a dataset with the velocity of attrition for 67 yard ultras in 2019. Just about 100% of members finished the 1st backyard or loop at each and every match. Past that, the proportion of race members who finished any next loop drops off sharply. Because the chart underneath displays, for many yard extremely races, the sphere used to be diminished via a minimum of part via the 16-hour mark. Only a few races had greater than 10% of members nonetheless operating after 24 hours. Giant Canine’s Yard Extremely used to be the notable exception. In 2019, it served as a championships match and used to be regarded as to have a deeper box of elite competition than some other yard extremely that 12 months.
That development used to be true throughout races, irrespective of match measurement. I have been curious if runners carried out higher after they registered for better occasions. I believed most likely a bigger crew of runners would inspire every different all over a minimum of the 1st 24 hours. I labeled occasions with fewer than 75 members as small, 75 to 100 members as medium, 100 to 174 members as extensive, and 175 or extra members as extra-large occasions.
Finally, it can be a query of private desire and technique whether or not a runner with aggressive objectives is healthier served via attending a bigger race, the place there’s a better pool of runners to doubtlessly run past 24 hours, or a smaller race, the place runners might have the benefit of a extra intimate get started/end space and not more congestion at the path.

The road graph above displays that for many yard extremely races, the sphere is diminished via a minimum of part via the 16-hour mark. Only a few races have greater than 10% of members nonetheless operating after 24 hours. Giant Canine’s Yard Extremely is the notable exception. In 2019, it served as a championship match and used to be regarded as to have a deeper box of elite competition than some other yard extremely that 12 months.
