Rachel was born and raised in Atlanta, GA where she attended Pope High School and walked onto the track team during her sophomore year – she credits this as one of the best decisions that she ever made. She then studied at Georgia State University, earning her Bachelors in Business Administration and Masters in Human Resource Management. In addition to working as a licensed agent at an insurance brokerage, Rachel is an ISSA certified Personal Trainer in the Atlanta area. When she is not training for, or racing, (or thinking about training and racing) she enjoys travel, outdoor adventures, cooking, watching scary movies, and is the proud mom of two rescued dogs. Rachel’s latest accomplishment, scoring an amazing 8th place in the 2018 World’s Toughest Mudder.

GBC pro team athlete – Lance Johnson

After picking up road running in 2014, Lance found himself wanting to push his limits even further. By the end of that same year, he began competing in various Obstacle Course Races and Endurance Events. After tackling his first Green Beret Challenge event in July 2015, he was hooked. He has since conquered numerous GBC events; including the Operators Course, the Commando Team Challenge, and Behind Enemy Lines (GBC’s 24-hour Endurance Challenge). Outside of GBC, he has competed in multi-lap races, ultra marathons, Tough Mudder, and GORUCK events. His fun-loving personality, passion for the sport, and continued success throughout the years made him a natural fit for the Green Beret Challenge Pro Team. Don’t let his size fool you though. He is a force to be reckoned with when it comes to heavy carries and running fast.
