Three hundred and forty bicyclists are pedaling furiously toward Jim Thorpe a legion of rail-trail aficionados on the 2010 Greenway Sojourn.

Riders on the Rails to Trails Conservancy's largest tourism event will cover 350 miles, pedaling 250 of those miles by bicycle.

On Tuesday, the Sojourn loosens up on a 20-mile completed section of the Schuylkill River Trail to the Berks County Heritage Center, just north of Reading. Since the trail is incomplete, a bus will ferry the Sojourn to Lehigh Gorge State Park Trailhead at White Haven for a 27-mile ride to Jim Thorpe.
