Bill VonderMehden has run the entire length of the Denali Park Road in one shot.
The 92-mile road cuts through Denali National Park and Preserve in Alaska.
The park is home to Mt. McKinley, North America's tallest peak.
It took him 25 hours and 20 minutes to complete the trek.
The Fairbanks Daily News-Miner reports he is believed to be the first person to make the run.
