The individual event is a solo 12-hour challenge. The relay is a 12-hour team event for up to four runners per team; teams may divide the 12 hours between members in any pattern they choose.
An Athletes’ Village is provided on site with space for tented support. Competitors have access to showers, on-site toilets, a café, and boiling water. Each entry includes chip timing, a finisher’s medal, first aid cover, and marshals.
