Tri the Rock 
This kid-friendly triathlon offers another outlet for your little athlete's energy. Three age divisions mean the youngest competitors (ages five to six) will only swim one pool length, bike one lap around Butterfield Crossing Park, and run about a third of a mile while kids as old as 14 can take on a 100-meter swim, an eight-kilometer bike ride, and a two-kilometer run. The food, prizes, and athletic activities will keep your children happy, healthy and, most important, occupied. If you sign up for the Give-Back program, $10 of the entry fee will benefit the physical education program at your child's school. Sun 8 a.m.
