Heldeberg Workshop, one of the most unspoiled natural settings in Albany County, is accepting applications for a free Wheelchair Archery Class at its outdoor Archery Field, 353 Picard Rd, Voorheesville, NY, on Saturday, October 17, from 12:30–3:30pm.
If you’ve ever wanted to try archery, this introductory course is designed for first-time para-archers or those exploring adaptive sports for recreation.
Instructors will guide you in shooting at various targets and different distances using light-draw bows and equipment provided by the Workshop. You’ll learn bow nomenclature, equipment use and care, shooting technique, and be introduced to different bow types.
This class is offered to adults 16 and older who use a wheelchair and can hold and shoot a bow without the help of adaptive technology. Participants may also bring a caregiver or companion, if they choose.
