About the venue:
Three miles southeast of Delano, CA, nestled in the vinyards and orchards of the Central San Joaquin Valley is Lake Woollomes, a 300-acre reservoir with 4 miles of shoreline, making it a cozy location for water recreation.
Swimming is allowed here, making this destination perfect for hot summer days. There’s also a boat dock and a launch ramp for those wishing to take to the water. But, the use is restricted to non-powered boats, so only sailboats, SUPs, and kayaks can be used on the lake.
This fast, flat course is the perfect place to get your next PR.
Note:
A USAT membership is required for the Triathlon, (but not the 5k/10k) If you do not have one, you can purchase one during the registration process.
