Welcome to the Silver State 508

September 12-14, 2025

A Race Across America produced event!

Founded by John Marino in 1983 and recognized as "The Toughest 48 hours in Sport," Silver State 508 is the world's premier weekend ultra cycling race. This 508-mile bicycle race is revered the world over for its epic mountain climbs, stark desert scenery, desolate roads, and its reputation as one of the toughest but most gratifying endurance challenges available, bar none.

Solo, two-person relay, and four-person relay divisions are offered, with sub-categories for standard bikes, tandems, recumbents, fixed gear, and single-speed bikes.

Silver State 508 is a Race Across AMerica (RAAM) Qualifier.

Silver State 508 starts and finishes in Reno, NV and crosses northern Nevada on Hwy 50, also known as "the loneliest highway in America."
