The history of Supercross in Denver is a tale of two eras, beginning with a brief debut in the 1990s followed by a modern resurgence at the home of the Denver Broncos. Because of its high elevation (5,280 feet), the race is famously known as the Mile High City round.

The Early Era: Old Mile High Stadium

Supercross first visited Denver for a single event in 1996 at the original Mile High Stadium.

The Race: It served as the season finale. Jeremy McGrath capped off his dominant 1996 season with his 14th victory of the year.

The Track: It featured one of the shortest starts in Supercross history because the venue owners required the track to stay off the primary playing field.

250 Class: A young Kevin Windham won the 125SX (now 250SX) Western Regional finale after already clinching the championship.

The Modern Era: Empower Field at Mile High

After a 23-year absence, Supercross returned to Denver in 2019 at the new Empower Field at Mile High. Since then, it has become a staple late-season round.

Historical Significance

Denver is often the penultimate round of the season, making it a "clinch site" where titles are frequently decided. As of 2026, no rider has won more than once in the 450SX class at this venue, highlighting the fierce competition the high altitude and hard-packed dirt provide.
