One 12 months in the past, skilled American path runner Michelino Sunseri of Driggs, Idaho, made a briefly-successful Quickest Identified Time (FKT) try at Wyoming’s Grand Teton Nationwide Park, protecting the 21-km round-trip path with 2,100m of vertical achieve in two hours, 50 minutes and 50 seconds. However precisely one 12 months later, on Sept. 2, 2025, Sunseri acquired a responsible verdict in federal courtroom for shortcutting the FKT route–a prison offence.

In response to his Strava add, Sunseri took Outdated Climber’s Path throughout his descent, a route used beforehand by mountaineers however marked closed for revegetation, to keep away from a switchback and shorten his route by greater than half a kilometre. Days after his try, the 33-year-old’s second of glory ended abruptly when the Nationwide Park Service (NPS) pushed prison expenses in opposition to him for violating a hikers’ code proscribing path use–a Class B misdemeanour, punishable by as much as six months in jail and a US$5,000 nice.
The trial lasted two days in Could, adopted by a three-month deliberation by federal choose Stephanie Hambrick, who issued her verdict final week. Sentencing will come at a later date; whereas jail time won’t be imposed, Sunseri might nonetheless face a nice or a ban from the park.
A rejected FKT
Unsurprisingly, fastestknowntime.com didn’t ratify Sunseri’s time, which might have crushed the earlier velocity file set by Andy Anderson in 2012 by greater than two minutes. “Based mostly on our dialog with the NPS and in accordance with our personal pointers, we’ve determined to reject Sunseri’s submission,” web site editor Allison Mercer instructed irunfar.com. “We don’t condone something that’s in opposition to the regulation.”
Jenny Lake district ranger Chris Bellino revealed that Sunseri’s excessive profile influenced the choice to pursue expenses. “We would have liked to ship a message,” Bellino mentioned in the course of the trial.

No penalty for Kilian Jornet
Sunseri’s FKT Strava add included an in depth account of his expertise and reasoning for reducing the course. “Operating up the final uphill of the route, I made the choice to chop the final switchback and keep away from the Congo line of hikers that may be heading up Lupine Meadows Trailhead,” he wrote. “If I needed to make this alternative once more, I might 100 per cent make the very same alternative. If anybody has an issue with that, they will go forward and inform Kilian Jornet that his time doesn’t rely, after which they will go run this path to the very best of their capability and beat all of our occasions. Or struggle me. No matter.”
In response to Outdoors, Spain’s mountain and path operating GOAT Jornet, who held the Grand Teton mark briefly earlier than Anderson, had used the identical shortcut throughout his makes an attempt–however confronted no prison expenses. Fastestknowntime.com flagged his run because of the shortcut, noting it “will not be allowed by the Nationwide Park, however is widespread follow in Europe.” The NPS later formally closed the shortcut, posting an indication that learn: “Closed for regrowth; shortcutting causes erosion.”
Interesting the decision
Sunseri’s authorized crew is interesting the decision, arguing that the path was not marked as closed within the downhill path. “[The ruling] reifies the large claims of energy by park superintendents to write down federal prison regulation,” Pacific Authorized lawyer Michael Poon instructed Outdoors. “That is nicely past any energy the Structure contemplates for inferior officers—these not confirmed by the Senate—to have.” All plea offers provided to Sunseri required him to confess guilt or face a ban from Grand Teton Nationwide Park.
Sunseri has additionally teased a documentary protecting the controversial FKT and prison expenses. The North Face athlete has even began a petition encouraging public assist for dropping the prison expenses. “These mountains imply every thing to Michelino,” Pacific Authorized acknowledged. “Agreeing to surrender such an integral a part of his life due to a regulation he didn’t know he was breaking was unthinkable.”
