The Fredericksburg event will offer 30-, 50- and 75-mile rides.
Local master naturalist Harry Puffenbarger will lead a nature hike through the Stratford landscape.
This schedule is anticipated to remain in effect through Wednesday, May 9, after which the Jackson Shrine will be open daily.
The festival was planned for last weekend, but technical problems with the projector curtailed the event.
