The event provides multiple support services. Covered rest stops appear roughly every 12.5 km, with a meal or larger food stop about every 25 km. Rest stops include seating, toilets, medical staff, massage and baggage pickup. The route is signed and marked and GPS tracking is available through the organiser app. A timing system scans progress at rest stops.
