On November 28-29, 2026, OnGrid is back at Thunderhill Raceway Park for a dual-track experience. One ticket gives you access to both tracks, each running independently, with a full day of driving per track. This day is built around seat time, good energy, and being at the track with your people. It’s two full day's of driving in one with plenty of laps to go around. If you can handle it, come drive all day.

  • This is NOT a 5-mile event.

  • Both race tracks will run concurrently but separately.

  • All drivers welcome

  • 18+ to drive or ride as a passenger in any vehicle (We allow 16+ on a case-by-case basis. Please email us at info@ongridtrack.com)

  • Passengers: Allowed

  • Camping: Friday & Saturday

  • Transponders: Not Available

Later Event: December 12
