2025 Spring Mountain Pit Spot Reservations

Reserved and Unreserved Pit Spaces - all cost the same!

A pit space is NOT included with your race entry, and whether reserved or unreserved, there will be a cost to everyone to pit at this event no matter what – so we highly encourage all attendees to reserve their pit spots ahead of time. And as usual, PKC Sponsors will be placed on the pit map ahead of non-sponsors.

The location of unreserved spaces will be determined on a first-arrived, first-served basis with no ability to choose a location or pit neighbor. As a result, you could arrive before gates open on Wednesday, Thursday or Friday morning and still be a lengthly distance from the pre-grid. Include in your pit spot purchase/reservation your top 3 choices of a pit location and we will do our best to accommodate you. Your assigned space will be available whenever you arrive. There is labor required to manage pit space reservations as well as pitting everyone upon arrival, so a cost is involved. 
  • Pit spaces for this event are $100 per spot, and parking will begin at 12:Noon on Wednesday. April 9th.
  • Again, PKC Sponsors will have priority pit placement.

OVERNIGHT CAMPING

  • RV camping IS allowed at this venue. Move in begins at 12 Noon on Wednesday April 9th. 
  • Camping fee is $300 per space for the event. Spaces are 20’wx40’D. 
  • All campers must be removed by end of day Sunday April 13th.
