After running for five years, I started participating in triathlons. Although I finished two events, I was far down in the pack due to my inexperience with both swimming as well as with the bike. I chose Cristina from a list of other coaches because she specifically mentioned that she used a science-based approach to her training, including data from training tools such as Garmin. Since I have a career in a science-based field, I knew that someone who wasn't up-to-date with current research wouldn't be a good fit for me. Too, she went to a D1 college as a swimmer, so I knew that she would help me with swimming.
