Across the Years

All races are held on a 1.05 mile loop at Camelback Ranch in Glendale, AZ.

However, due to the increased capacity at Camelback Ranch, in 2011 the lottery was removed and registration was once again offered to all on a first-come, first-served basis.

Founded in 1983 by Harold Sieglaff, the race has changed over the years in location as well as organization.

Until 1993 the race was held at Washington High School in Phoenix, after which it was moved to different locations, including a 500-meter certified loop at Nardini Manor in Buckeye, AZ from 2003 until 2010.
