The revenue streams for ultra endurance racing and event management comes down to the participants themselves, who Steve Fleck believes are some of the sport's biggest fans. Fleck talks about the way in which endurance racing, including marathons and Iron Man competitions, have grown and potentially plateaued over the last few decades. Coupled with that is the technological aspects that have both improved the audience experience at the larger events, but created unrealistic expectations by fans when attending smaller events. Fleck talks about some of the issues surrounding endurance sports, such as Tough Mudder, and whether they are pricing themselves out of the marketplace through participant fees. Twitter: @SteveFleck
