Swim 2.4 miles, bike 112 miles and run 26.2 miles over the course of the summer. Track your progress on provided logs, then turn in by the end of the summer (July 31) for a t-shirt. Register at Sports*Com from May 1-May 31. For all ages.

Summer nights are great for spotting owls and bats, listening to a chorus of frogs and insects, discovering glowing eyes and finding fascinating critters that become active at night. Join us throughout the summer to discover the forest under the night sky. Reservations are required. For all ages.
