Swim 1.5K, bike 40 more and then run 10K. For non-swimmer Valicity "Visa" Lattimore, who hadn't ridden a bike for years, it seemed impossible. Yet she completed her first Olympic-distance triathlon after training with TNT for just 15 weeks. The inspiration? Her son, William, now 9 years old, an acute lymphocytic leukemia survivor who says he's "thankful to be alive" and thankful to mom and everyone who participates in Team In Training.
