About this event

The park opens its gates at 8am.  We will have a wave of pre-registered runners start at 9am.  Race day registration will be available at 8:45am.  T-shirts are not available for race day registrations.  20-person waves for race day registration will be first-come, first-served and start around 9:15am, 9:30am, and 9:45am. We only have 60 race day registration spots available. Parking is guaranteed for all pre-registered runners. Parking for race day registration is first-come, first-serve. Parking space capacity is only 123 vehicles.  They have typically hit max capacity around 9:45-10am.  The park has assured us that there is "a high-probability that if runners arrive before 8:30am, they will not be turned away."  We will have 3 water stations for the 10k and 1 for the 5k.  We recommend bringing your own water.
