About
Butterfield Trailhead Regional Park sits in the shadow of Kennecott Mine and the Oquirrh Mountains. This park is new and designed to give access to the new Butterfield Trail system as well as host events both big and small. We will be setup in the event parking which will provide plenty of room for Blitz Backyard runners to get comfortable and settle in for the long and fun day. We hope you come out to push yourself and have a good time with friends and family at the finish line.
Save Butterfield Blitz Backyard to your season and RunCalendar reminds you the morning entries open and before they close. Free on iPhone, no account needed.
