Embrace the Challenge

ZACH MACH Mackay Adventure Challenge


If you are over 15 years of age on the day of the event come and join our amazing team of volunteers. Bring your family and friends up the Pioneer Valley to sit under a tree, on a river bank or near the Pinnacle Hotel for the day.

Many hands are needed to cheer on competitors, hand out water, fill in paperwork, move things, sweep stages, provide first aid, drive vehicles, set up and take down signage, refer incidents to officials, be a visible presence on the course, etc.

Please help us make the ZACH MACH be truly memorable and Volunteer Today.

Our Volunteers receive Cookies, Fruit, Bottled Water and a FREE Pinnacle Pie post shift.
