Teens from across the Pittsburgh region are gearing up for an "ultimate" fund-raiser to sponsor outdoor recreation opportunities for area youth and families.

The fund-raiser, titled Powered by Pittsburgh, is a project of the NRG Powered by Choice program, a teen campaign across 49 counties to make being healthy easy. Hundreds of area teens are expected to participate on April 25.

"We're really excited about this, especially since it's taking place on Global Youth Service Day," said Danielle Sunday of the Penn State Hershey Center for Nutrition and Activity Promotion. "I think it's going to be a lot of fun, and I hope a lot of kids come out, be active and help us reach our goal."

Ultimate Frisbee is the signature fund-raising sport of the campaign, sponsored by Highmark Healthy High 5, an initiative of the Highmark Foundation.

The minimum-contact sport is a hybrid of the traditional flying disk toss, football, soccer and rugby, hence the nickname the "ultimate sport." It's popular in fund-raising, Sunday said, because it's easy to play, even for beginners.

The goal of the event is to raise at least $2,500 dollars by bringing together 250 participants. Funds will be raised through entry fees -- $10 per participant or $100 per group.

The event, hosted by the Penn State Hershey Center for Nutrition and Activity Promotion, will be held from 10 a.m. to 5 p.m. at Allegheny Commons, Richie McCabe Field in the North Side.

Venture Outdoors, the Pittsburgh-based nonprofit group dedicated to increasing outdoor recreational activity, will use money raised to purchase kayaks, bikes and other physical activity equipment.

Teens interested in participating can sign up at www.poweredbychoice.org. No experience is necessary; sneakers or cleats are required to play. Members of the Pittsburgh High School Ultimate League will be on hand to teach the rules and give basic lessons.

Winners will receive NRG Powered by Choice Nike Dri-fit shirts, and each player will receive an NRG Powered by Choice lanyard and certificate of completion.

Activities for participants between games include free climbing walls, mountain biking and fastest throw competitions.

More than 300 Pennsylvania schools will also host tournaments on their own throughout spring to raise money for healthy improvements in their schools.
