The event operates as cupless; runners must carry their own bottle or reusable cup. Reusable silicone cups will be available for purchase at the event for $5. Runners are strongly encouraged to carry at least one 20 oz bottle.
Parking is available free of charge at Lake Anza. The event has a combined capacity of 350 runners across all distances. The 50K distance has an overall time limit of 8.5 hours.
