XTERRA World Championship

The world’s premier off-road triathlon, combining a 1.5-kilometer (1-mile) swim that starts in front of the Makena Beach & Golf Resort a 32-kilometer (20-miles) mountain bike that climbs 3,000 feet up and down the lower slopes of Haleakala, and a 12-kilometer (7.5-miles) trail run that traverses lava rock, forest trails, and beach sand. Top pros finish in roughly two-and-a-half hours.
