From our Postcards from Boston Series: Mary Beth Ellis, the 2015 ITU Long Distance Triathlon World Champion joined us for a chat at the Boston Marathon Expo. Mary Beth explained how she got the nickname the Honey Badger from her Coach Brett Sutton. She talked about what she learned from training with greats like Chrissie, Rinny, Daniela, and Nicola. Now retired from racing as a professional, Mary Beth is coaching, and chatted about how much she is enjoying working with age-group triathletes. We also talked about Mary Beth’s running background (she ran at Northwestern), and how over the years, she has learned the value of cross-training.
