Point-to-point course
You finish in a different place than you start, so plan for transport back to your car or lodging.
JAC is a small airport with limited direct flights and higher fares; rental cars recommended. Race-morning shuttles are mandatory (no personal vehicle access to start or finish), adding a logistical layer. Jackson has good lodging but books early for race weekend.
Fly into JAC or drive. Book lodging well in advance — race weekend coincides with peak early-summer Jackson Hole tourism. Pair with Grand Teton NP (30 min north) or Yellowstone (90 min north) for a full destination trip.

First-timer mistakes
Underestimating the altitude (6,100–6,350 ft) is the top mistake — even a flat course feels hard at elevation. Also, forgetting to bring a reusable cup or hydration vessel will leave you unable to drink at aid stations; the race is zero-waste with no disposable cups provided.
