Like David and Andrew, Gino is passionate about cycling and regularly competes in the 50+ and 55+ Master’s Category in the Mid-Atlantic Bicycle Racing Association (MABRA).

Dave Johnson has served his country in the Navy for over 30 years. A 1982 USNA undergraduate and MIT graduate, he is a marathoner, triathlete and biker. He’s run 10 marathons, culminating in the 2001 Boston Marathon. Since then, he’s competed in a half dozen Sprint and Olympic length triathlons, many road century rides and in 2013 – Race Across America on Team GBF – a 4-man, over 50 military team. He’s also done 40k TT’s, nearly breaking the hour barrier and the Jeremiah Bishop Gran Fondo in Sept 2014 – 108 miles with 11K ft of climbing – mostly on dirt. That got him interested in doing the Leadville 100 MTB Race in 2015. He’s a father of three daughters, has two grandsons and son-in-law and has been happily married almost 30 years. Around family, church and a very demanding work schedule, he finds the time to keep in shape by riding his trainer during the week, some running and gym time and putting in the distance miles biking with his RAAM teammates on the weekend – all under the direction of his RAAM coach Sue Hefler (www.heflerperformancecoaching.com).
Andrew graduated from the Virginia Military Institute in 1990 with a degree in Mechanical Engineering and a reserve commission in the Army. Shortly after commissioning he attended and graduated Army Flight school as a rotor wing pilot and served the following 6 years as platoon leader and company executive officer in his local National Guard aviation unit.
Andrew now owns his own engineering and consulting company and is currently supporting the Under Secretary of the Army on various transformational initiatives.
He has been a life long cyclist (road and mountain) enthusiast. Most recently he has been competing in various adventure races and ultra endurance mountain bike races across the country. He is also an avid runner and just completed the 2012 Marine Corps Marathon in 3hr 31min. Andrew is a dedicated husband and father of 6 children all of which are following in his fathers’ footsteps as an athlete. Andrew is also coached by Susan Hefler of Hefler Performance Coaching.
