Holland, a horse veterinarian who works at the Palm Beach Equine Clinic in Wellington, is a member of the Leukemia & Lymphoma Society's Team in Training.
In exchange for coaching and support, athletes help raise money for causes such as leukemia, the No. 1 disease killer of children.
Holland is training to run in a Walt Disney World triathlon on Sunday and must raise at least $2,500. She also plans to enter a Disney marathon in January and must raise another $2,500.
Team In Training, which has a Palm Beach Gardens chapter, started in 1988 when Bruce Cleland of Rye, N.Y., formed a group to run in the New York City Marathon. He wanted to honor his daughter, a leukemia survivor.
