Runners and hikers are invited to participate in the Sierra Club - Lancaster Group’s seventh annual Polar Bear 5K Trail Run/Hike, beginning at 10 a.m., January 14, in Lancaster County Central Park, winding through the park on well-maintained trails with some hills. Race day registration and check-in will begin at 8:30 a.m., at the park’s Pavilion 22 (Kiwanis Lodge). Dogs on a leash are welcome to run or walk with their owners.

All funds raised by the Sierra Club - Lancaster Group’s major fundraiser support local efforts to help people better appreciate, protect and preserve the environment. The funds will help subsidize their green project grant program, which awards grants of up to $500 to Lancaster County organizations, and supports its outdoor activities and educational programs to end global warming.

More than 270 hikers and runners registered for the 2016 race, while scores of volunteers were on hand to make the event possible, and 65 very cheerful dogs ran or hiked with their humans.

The Sierra Club is a national nonprofit organization with each state having its own chapter. The Lancaster Group, one of ten within the Pennsylvania Chapter, has approximately 1,100 members.

Cost: $30; $25 if registered by December 21. Pre-register by January 4 to be guaranteed a t-shirt. For more information, email [email protected] or visit LancasterSierraClub.org or Facebook.com/SierraClubLancaster.
