Rob Leishman

Race director of Kiss Me Dirty, Leishman saw the growing popularity of obstacle courses about two years ago and decided to put a spin on it and add some mud. Starting out in Utah, KMD now has more than 10 events across the country benefiting local gynecological cancer research. "We're bringing an interesting twist on the good ol' fashioned get out and stretch your legs," said Leishman.

Anita Kellman

With more than 25 years of experience in the medical field and as a clinical liaison for patients, Kellman knows about the importance of staying active. Founder of Beat Cancer Boot Camp nine years ago, Kellman added the Beat Cancer Boot Camp Challenge four years later when she was looking for a way to raise funds and involve the community. The boot camp is not just for people fighting or recovering from cancer: It is open to anyone who wants to be a part of her physical support group promoting a healthy and positive lifestyle. More than 750 people have taken part in her boot camp challenge, which is now a national program in six states.

"It is open to anyone to participate. That's the whole idea. They can come as an individual or a squad, and they can get personalized bibs," Kellman said. "Really, it's a community event."

Lorey Pro

Pro has been the assistant director of fitness and wellness at the University of Arizona's Campus Rec Center for seven years. She develops personal training and group fitness programs, specialty classes and off-site, fitness-related events. A tri-athlete, she recently introduced a Warrior Training class that specializes in preparing for obstacles courses and mud runs.

"When you cross the finish line, there are two possible reactions. One, I can now cross this off my bucket list; or two, I can't wait to sign up for my next race," Pro said.
