TRIBY3 coaches

Greg Close
  • USAT Level 1 Coach
  • Level 3 USA Cycling Coach
  • USATF Level 1 Coach
  • POSE Method of Running Instructor
  • Slowtwitch Certified Triathlon Swim Coach
  • Professional Triathlete

Greg came to multisport events from the world of rowing in which he competed for the Rutgers University and Pennsylvania Athletic Club lightweight squads. While working to win three Canadian Henley titles and numerous National Championships, Greg also spent his eight years in rowing coaching athletes of all ages and abilities. After graduating from Rutgers, Greg went on to coach rowing while getting his M.A. from Lehigh University. At Lehigh, Greg began to cross-train with cycling and running, and in 2005 decided to test his fitness in a triathlon for the first time, and he was instantly hooked.

After a successful amateur campaign with a few National Championship titles and a couple World Championship medals, Greg transitioned to professional racing in 2012. Focusing primarily on the long course distance, Greg has a PR of 4:04 in 70.3s (Eagleman) and 8:49 in 140.6s (IMCHOO).

Throughout his personal athletic endeavors, Greg has always had a commitment to coaching. Whether conducting a middle school learn-to-row program or coaching Division I collegiate rowers, teaching a lifelong non-athlete how to conquer his first half-marathon or preparing an experienced runner to break her personal best, Greg’s love for athletics is as much about his own athletic achievements as it is about finding and fostering the athlete in others.


Darbi Roberts
  • Professional Triathlete
  • USAT Level 1 Coach
  • Total Immersion Swimming Certified Coach

Darbi comes to TriBy3 with the most diverse athletic background of all of our coaches. Darbi was a competitive swimmer for years as a child, and rowed for Carnegie Mellon University in Pittsburgh, PA. Following graduation, Darbi played Rugby 7’s in Qatar for 3 years. While there, she developed a love of long-distance cycling and running, and–coupled with her strength as a swimmer–translated that into triathlons when returning stateside in 2010. Darbi finished as 1st amateur woman at Ironman Louisville in 2012 (her first Ironman) and blew onto the national stage from there. She repeated the feet again at Ironman Mt. Tremblant in 2013, placing in the top 10 overall women (pro and amateur). After finishing 5th in the women’s 25-29 Age Group at the Kona Ironman World Championships in both 2012 and 2013, she began competing as a professional in 2014. Top finishes since turning pro include Syracuse 70.3 2014 (3rd FPRO), Princeton 70.3 2014 (3rd FPRO), IM Barcelona 2014 (8th FPRO), IM Arizona 2015 (4th FPRO with a PR of 9:05:310 including a 4:55 bike split and a 51:41 swim split), and Darbi is the 2016 Ironman Wales CHAMPION (PR swim of 49:30). She also is the owner of a 3:03:08 marathon PR (Philly 2013) and has her eye on the 3 hour barrier.

Darbi’s coaching experience is similarly diverse, having worked with swimmers, runners, soccer players, and rowers of all ages and experience levels over the past 10+ years. Her love of coaching and teaching carries over into her academic and “alternative” professional life (sometimes she wishes it wasn’t alternative!), too. Darbi is an Assistant Dean at Columbia University’s School for International and Public Affairs and holds a doctoral degree in International Education Development from Teachers College. She is a firm believer in work-life balance and is confident that even the most busy professionals, parents, or students can find time in their day to practice the YFTYT™lifestyle.

Laura Barbieri
  • Elite Amateur Triathlete
  • Four Years of Coaching Experience

In 2004, after finishing graduate school for classical music performance, Laura joined a running group with the singular goal of completing a marathon.  She quickly became immersed in the sport, completing over 20 marathons, including four Boston Marathons.  She eagerly jumped into triathlon at the Half Iron distance in 2007, and in August, 2009, four months after undergoing major surgery and while battling major physical impediments, she completed her first of three iron-distance races at Ironman Canada in Penticton, BC.

As an athlete, Laura has achieved success in her age group, including multiple podium finishes and top bike splits, over a wide range of distances.  In 2014, She qualified for the 2015 Ironman 70.3 World Championships with a top ten age group finish at Timberman 70.3, going on to compete in the World Championship race in 2015 in Zell an See Kaprun, Austria.

Laura’s experience in the sport has underscored her belief that no goal is unattainable and no limit too high with a passion, a positive mentality and dedicated, consistent work.  She brings this mindset with her as a coach, and encourages the same in the athletes she works with.
