Olympic track cyclist Kelly Catlin died Friday. She was 23.
"There isn't a minute that goes by that we don't think of her and think of the wonderful life she could have lived," Mark Catlin, Kelly's father, wrote to VeloNews. "There isn't a second in which we wouldn't freely give our lives in exchange for hers. The hurt is unbelievable."
Mark Catlin said his daughter killed herself. She was found at her home in California.
"The entire cycling community is mourning this immense loss," USA Cycling chief executive Rob DeMartini said in a statement.
