About Mary Beth Ellis
Born 1977. Mary Beth Ellis is an American triathlete.
Athletic career Ellis was born in Washington, D.C., and raised in Rehoboth Beach and Lewes, Delaware by Stephen and Kathleen Ellis. She attended Lawrenceville School where she competed in swimming, golf, lacrosse, field hockey, and track and field. Ellis went on to college at Northwestern University to major in industrial engineering and then obtain a master's degree in marketing. While at Northwestern she competed on the school's cross country team and was a four-year letter-winner and NCAA qualifier for the NU swimming team. It became apparent that Ellis was more suited for longer distance triathlon events versus shorter, Olympic style racing. and Ironman Cozumel.
In 2013, Ellis continued to have more success by winning Ironman 70.3 Florida, defending her title at the Alpe d'Huez Triathlon, and claiming first place at both the Ironman France and Ironman Mont Tremblant races; which continued her steak of remaining unbeaten at Ironman races outside of the Ironman World Championships. On September 9, 2013, while training for the upcoming Ironman World Championship in October, Ellis broke her collarbone in a bike accident in Cozumel, Mexico. After the injury, she initially felt that she wouldn't be ready to compete in the 2013 Ironman, but that changed after undergoing surgery. Ellis' condensed a four to six-month recovery plan into one month with the goal of competing in the October 12th race in Kona, Hawaii. She used the crash experience to raise money for the Steadman Philippon Research Institute, the nation's largest and oldest non-profit for sports injury research. In Kona, Ellis came into T2 in 15th place after the bike, but was unable to finish and compete in the remainder of the race.
Following the crash Ellis changed her perspective towards racing and as a result changed coaches, opting to again work with Lindley. For her 2014 season Ellis decided to take on a "triple-crown" of non-drafting championship races; the 5150 Championships, the Ironman 70.3 World Championship, and the Ironman World Championship However, these races, as well as others for the next 18 months did not produce the finishes she was hoping for. Despite her praise of Lindley as a coach Ellis recognized that her time left as elite athlete was limited. Therefore, she re-enlisted Sutton as her coach in May 2015 hoping to reproduce the same successful race results she did under his previous guidance. In an indication that her training and racing under Sutton was progressing in the right direction Ellis won the ITU Long Distance Triathlon Championships in late June, leading the race from start to finish.
In October 2016, prior to competing at the 2016 Ironman World Championship, Ellis announced this race would be her last as she would retire from the sport of triathlon as a competitor. She expressed a strong desire to give back to the sport and entering into coaching alongside Sutton. In her final race Ellis placed 14th.
