Climb 89 is a hill-repeat running challenge at Badger Mountain Westgate Trailhead in Richland, Washington. The concept is to ascend the same short pitch repeatedly. The route measures 0.35 miles one way, with each lap gaining 89 meters (292 feet), causing the elevation gain to accumulate rapidly. Participants run out and back on the marked course as many times as possible within the event duration. The 100-lap option totals approximately the height of Mount Everest.
The lap benchmarks provide the race's framework: 13 laps equate to Rattlesnake Mountain, 29 to Mount St. Helens, 50 to Mount Rainier, 70 to Denali, 85 to Annapurna III, and 100 reaches the Everest benchmark of 29,032 feet. Prizes are awarded based on laps completed, allowing participants to target a smaller mountain or continue toward the full Everesting distance. Delta Endurance LLC organizes the event, offering food and snacks. A cash prize is available for setting a course record, and finishers achieving the Everest-level ascent can seek entry into the Everesting Hall of Fame.
