Cheddar's Brad Smith sits down with Tough Mudder HQ senior vice president Cathrin Bowtell to discuss the brand's expansion. The company is opening Tough Mudder Bootcamp studios in Massachusetts, Nevada, and Texas.

Bowtell says the brand is focused on Tier 2 and Tier 3 markets. She explains this isn't a play for big cities like New York or Los Angeles since 69% of people who run Tough Mudder races live outside the top 10 U.S. urban areas.

Bowtell says Tough Mudder has tons of loyal customers which makes franchising easy. She wants Tough Mudder Bootcamp locations to be more accessible and relatable than some of the boutique studios that are popular right now.
