Hillary Biscay is the most prolific iron-distance competitor on the professional women’s racing circuit. She has 58 iron-distance finishes to date and often races ironmans on back-to-back weekends. In fact, she won her first ironman in 2008 at Ironman Wisconsin just a week after finishing a close 4th at Ironman Louisville. In 2006, Hillary set a standard in Ironman racing by becoming the first person to record six top-five Ironman finishes in one season. She now has 18 podium finishes and 30 top-5 finishes at the ironman distance to her name.

In 2010, after completing 8 ironmans during the season, Hillary took on a new challenge at the Ultraman World Championships in Hawaii. She finished second and recorded the fastest women’s Ultraman debut in history, while also finishing over an hour under the 21-year-old course record time. Hillary also owns the women’s swim course record with a time of 2 hours 20 minutes for 6.2 miles.

Having competed in the 2000 US Olympic Swimming Trials (200-meter breaststroke), Hillary is known for her swimming prowess, and often leads out Ironman swims. She was the also the women’s swim winner at the 2008 Hawaii Ironman World Championships.

Hillary competed as an age-group triathlete for four years before turning pro. During this time, she was teaching at the University of Southern California and working on a Ph.D. in American Literature. She put this degree on hold to try to turn her triathlon hobby into a livelihood and hasn’t looked back!

Hillary also spent three years under the tutelage of Brett Sutton (Team TBB), and credits what she learned as part of his squad for much of her success.
