Because Cristina is an endurance athlete herself, she knows how to fuel, and what it feels like when you aren't fueled correctly. To her, no food group is an enemy. In fact, she likes to tell me that food is fuel. I especially liked that it felt safe to disclose my past history with disordered eating, so she could help me figure out how to eat for nutrition and to lay down some of the baggage. She is a fun and low-key coach – she can go all-out harder than I can, but I never feel like I'm out of my depth.
