A competitor who officially finishes the Trail 100 Run, Trail 100 MTB, the Marathon, the Silver Rush bike or run, and the 10K is called a "Leadman" or "Leadwoman", a title which nods to the Ironman Triathlon. Charles Bybee currently holds the most Leadman titles, with 10 years of finishing all events (2007-2010, 2012–2017). In 2015, Junko Kazukawa completed the Grand Slam of Ultrarunning and the Leadwoman series, becoming the first person to complete both events in a single year. In 2019 Dion Leonard became the first male to complete the Grand Slam of Ultrarunning and the Leadman series in one year.
