  • Full Competitive Course = ~5,000' vertical comprising three circuits of: skintrack to top of Thunderbolt (but well shy of summit), partial ski descent, followed by short bootpack, then the remaining descent.

  • Just before the winter closure of Thiel Road, turn left to continue along Gould Road, alongside which you can park.
  • Registration & bib pick-up at the map's starred gazebo location, which is visible from the road.
