The 508 - The toughest 48 hours in sport!

September 2025!

Team NZBLUE is back on the bike in Boreggo Springs Desert, California for what is billed as the toughest 48 hours in sport.

Mid September 2025 Team NZBLE will once again head to Southern California to compete in the iconic “508” Raising the profile and much-needed funds for the I am Hope Foundation, this endurance cycle race in the Borrego Springs Desert and hills of Southern California will be one tough challenge for the boys from down under. 

Founded by John Marino in 1983, The 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, low traffic roads, and its reputation as one of the toughest but most gratifying endurance challenges available.

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.

The 508 is a Race Across America Qualifier.

Participants will start/finish in Borrego Springs, CA, a community of 3,500, roughly 90 miles NE of San Diego. The small community is an “in-holding” in the Anza Borrego Desert State Park, California’s largest State Park, the second largest in America.
