Born in Spokane, WA, Greg was raised to about 5’9″ in Six Mile Bottom, England (near to, but farther than four miles from, Two Mile Bottom, England). While his dad taught at RAF Lakenheath, he ate Marmite and scones for about 15 years.
Greg’s first sport was swimming, starting at age 8 with the Lakenheath Barracudas. He knew he was destined for greatness after he won the boys under 9 50m butterfly Suffolk County Champs. After graduating from homeschooling (top of the class), he trained with West Suffolk Swimming Club and Cambridge University Swimming Club throughout high school. He competed at Age Group Nationals in the 200m backstroke from 11 until 14, when he joined the Track and Cross Country at Lakenheath High School. A National Champion XC runner, he continued running at Wake Forest University under coaches Brad Hunt and John Millar.
His triathlon career began at age 10, at the first RAF Lakenheath Triathlon when he rode a tandem bike ride with father Billington. Greg began racing for the US in the ITU Elite Junior Worlds in 2006 and won multiple U 23 National Championships. After competing at the Olympics in 2016, Greg retired in 2017 to help the world get cashback by working at Visa.
Although Greg stopped training he retired, he found himself drawn back to the sport as a way to manage stress and improve work performance. He took up marathoning - much less time consuming than triathlon. Greg raced at the US Olympic Marathon Trials in 2020, finishing 37th at 2:17:21.
Greg is passionate about sharing what learned as a professional triathlete to help other corporate athletes maximize how they use sport to be healthy and successful.
