The Kona to Mauna Kea Sea-to-Summit 100km (plus a bit): The route starts at the Ironman Championship start line at the beach in Kona and ends at the summit of Mauna Kea, the highest point in the state of Hawaii. It is 63.5 miles with about 15,000’ of total vertical gain and a final elevation of 13,800’. 100% of the route is running/hiking along public roads, and there is no race site that tracks this route, so it meets the basic qualifications for an FKT route.
