Jefferson Mountain Bike Association (JMBA) formed in April of 2012. We are a local chapter of the International Mountain Biking Association (IMBA). Our mission is to preserve, produce and promote amazing mountain biking experiences in the Yreka area.
A dedicated group of mountain bikers saw both a need and an opportunity for the future of mountain bike trails in and around the Yreka area. Greenhorn Park in particular is a favorite to mountain bikers both old and new to the sport. Our club members recognized the significant work of the crews that built the original trail system. As the sport continues to grow in popularity and as bicycle tourism efforts hope to make our community a cycling destination, the JMBA will take on a leadership role in maintaining existing trails and building new trails. We recognize that many of our trails are used by cyclists, hikers, runners, and horseback riders. As a chapter of IMBA, we are dedicated to ensuring safe and enjoyable trail use for everyone.
Some of JMBA’s current and future projects include:
• Humbug Hurry Up Mountain Bike Race - June 28, 2014
• Built 1400 feet of new singletrack trail in Upper Greenhorn - Now part of Humbug Hurry Up
