Holdridge Professional Review and Guide

"Holdridge is a labor of love by a few intrepid mountain bikers (Kirk Costello, Ed Kohlman, Randy Estes, Paul Gruber, and Rick Jerrell, along with other family members and volunteers) who decided to develop a trail system on some public land that the state representatives offered access to. Sometime around 1991, a group of riders set forth to build some single-track on a rough tract of land used for hunting, horse trails, and two-track access to ponds. They put together the three loops and built the parking area and pit toilets all as volunteer labor. Over 20 years later this is still an actively used and maintained mountain bike area and one of the largest (and most challenging) in the region.

Holdridge is really three different mountain bike trails in one. The North Loop is short and easy, the West Loop is moderately challenging with a slightly more challenging technical section, and the East Loop, often known as Gruber’s Grinder, is a highly technical and longer trail for the advanced cyclist. There’s something for everyone here."
