Online: Red Sports runs the live timing and official results on raceresult. Here are the 2026, 2025 and 2024 results. The FIM Hard Enduro World Championship posted a 2026 weekend recap video on its YouTube channel.

Hard enduro at Silver Mountain started in 2016 with the Stix & Stones Silver Mountain Xtreme Challenge, run by Greg Ragsdale. The 2020 race was cancelled because of COVID. The 2021 race was the fifth. It drew 525 racers, and Trystan Hart won the pro men's class.

In 2022 James Stearns and Inside Enduro took the event over and ran it as Silver Kings for the first time, on 18 and 19 June. Nearly 400 racers entered. Keith Curtis won on a Sherco SE 300 two-stroke, 38 seconds clear, in under three hours. The purse was US$20,000.

In 2023 Hart won his first Silver Kings in under three hours on a one-lap course with a six-hour cutoff. Ryder LeBlond was second, 40 minutes back, and Cody Webb was third. All 500 entries sold out six weeks early.

In 2024 the race was decided on combined time over two days. Hart won in 6:31:26.55, ahead of LeBlond (6:53:57.46) and Will Riordan (7:04:15.19). Only three Gold riders reached the finish, according to Cycle News. Sandra Gómez won the women's pro class. It was the first North American race timed on the raceresult system.

In 2025 Silver Kings was round 2 of the FIM Hard Enduro World Championship. The FIM brought in a new points system at this round. Mitch Brightmore won the Super Kings final. Hart won the first mountain day. Manuel Lettenbichler won the main race by about 20 seconds from Hart. The King Slayer finish climb was cancelled, so results used the last checkpoint all riders had passed correctly. Lettenbichler took the overall from Hart and Brightmore. Wade Young was fourth and Mario Román fifth.

In 2026 Brightmore took his first world championship win, 5.55 seconds ahead of Hart.

Trystan Hart has the most Silver Kings wins, with two. He won in 2023 and 2024 and was second in 2025 and 2026.
