Transition - Location for 2025
Transition will be moved this year to the boat launch area.. The bike out and in ramp to Electric Ave will be closed to cars and all cars entering and exiting the park will utilize the (typical) entrance to the park. We will have cones and course marshals directing athletes. Overflow parking will still be on the grass field.
Wave Start Times 2025
