Big Blue Adventure
Big Blue Adventure challenges athletes of all experience levels with races in scenic venues throughout California, Idaho, and Nevada. Trail races take runners along paths with stunning views of rivers, lakes, and beaches, and Adventure Races, which sometimes last more than 24 hours, combine running with activities such as mountain biking or kayaking through clean water. All of the races are sanctioned and insured by USA Triathlon. All of their upcoming races can be found on their event calendar.
