The Lead Left: Jason, your new book, Sweat Equity, focuses on endurance sports and the fitness industry from the entrepreneur’s perspective. What was the inspiration for this project?
Jason Kelly: It was both personal and professional. I’ve been running marathons since 1999, I started looking at how dollars were being spent. Running is simple, not a complicated sport. You basically have shoes and clothes. I realized I was spending a lot on not just those basic items, but also the cost of races, your travel, your food, and so on. And I was spending a lot!
