The South Bay Sprint and Olympic Duathlons, with a Run-Bike-Run format. These races will give new and tenured athletes a great opportunity to prepare for the upcoming triathlon season or just enjoy an endurance event in the bay area. This moderately flat and fast course will set the stage for a great finish. We kick off the spring season with a race that will get people ready for a great summer of USAP Events in Northern California. Come out and participate in one of the largest duathlons in the country.
