Earlier this year, athlete Michelino Sunseri appeared to break the 12-year-old fastest-known time (FKT) record for the Grand Teton in Wyoming, Snow Brains reports.
On Labor Day, Sunseri completed the challenging 15-mile route, which involves a climb and descent of 7,000 vertical feet, in an impressive 2 hours, 50 minutes, and 50 seconds—surpassing the previous record by more than three minutes. However, the achievement quickly became embroiled in controversy when Sunseri admitted to cutting a switchback during his descent.
The switchback, connecting Garnet Canyon to Lupine Meadows, is the largest on the descent route. Cutting it violated National Park Service (NPS) regulations, which are designed to prevent environmental erosion. As a result, the Fastest Known Time (FKT) website, which verifies such records, rejected Sunseri’s claim. Grand Teton National Park rangers have since confirmed that Sunseri was issued a citation and formally charged for violating park rules by disregarding posted signs and cutting the switchback. The misdemeanor charge carries a potential fine of $5,000 or six months in jail. Sunseri is required to appear in court on November 19.
The revelation of the shortcut has sparked debate in the mountain running and climbing communities. Critics argue that Sunseri’s actions undermine the integrity of his accomplishment. Cutting switchbacks is illegal in US national parks due to its environmental impact, although the practice is more common in some European races. David Gonzales, a writer and photographer, emphasized that following the official route is crucial for maintaining credibility in speed records. Jackson-based runner Kelly Halpin also voiced disappointment, noting that Sunseri was aware of the rules.
This is not the first time a Grand Teton FKT attempt has stirred controversy over switchbacks. In 2012, renowned mountaineer Kilian Jornet faced similar backlash after cutting switchbacks during his attempt. The incident prompted Grand Teton National Park rangers to issue warnings, stressing that anyone caught cutting trails would be ticketed.
