On a hike a few years back, John O'Meara shared with me his arduous quest to summit the tallest peak in each of the United States. Looking back, it seems like child's play compared to his next adventure outing - climbing Mount Everest.

The Metro Parks executive director will train for the ascent Saturday at Clear Creek Metro Park, and he's inviting advanced hikers to join him on a strenuous 15-mile trek over the preserve's notoriously difficult terrain.

Participants should bring sturdy footwear and a daypack with at least two liters of water and high-energy snacks. Reservations are required, and the group will be capped at 25. Meet at the Creekside Meadows picnic area.
