Experience two days of exhilarating off-road adventures at Stewart State Forest’s Dirty Double Challenge! Spanning 80 miles over two days, this unique race offers both mountain bikers and gravel riders an unforgettable experience. Whether you join for a single day or tackle the full event, you'll compete on two distinct courses designed to showcase the diverse terrain of Stewart. On Saturday, August 1st at 9am, the Gravel Course invites participants to navigate through three 13-mile loops. While most of this route is paved with fast service roads, there are enough technical single-track sections to keep mountain bikers engaged and in the mix. To ensure a smooth ride on these challenging surfaces, consider using tires with at least 38mm width for optimal traction. The only aid station along your journey will be Ridge Rd, which you’ll pass multiple times and where the party atmosphere is sure to energize you. For those looking for a more technical challenge, Sunday’s MTB Course awaits starting at 9am on August 2nd. This course covers approximately two laps of about 20 miles each, featuring fast, flowy XC trails with just enough service road sections to break up the action. The Dirt Crew has meticulously maintained these trails in top condition; be sure to acknowledge their hard work as you traverse them. After completing your race, head over to Bikeway Bicycles (628 NY 17K, Montgomery NY) for an after-party filled with local food trucks, vendors, raffles, and live music. Free tent or car camping is available just a mile from the finish line at Bikeway Bicycles! To secure your spot, contact Bikeway Montgomery at (845) 787-4082; spots are limited to 50 participants. Parking for both days will be available in Stewart State Forest along Maple and New Rd. The first 250 vehicles can park here without issue. For those attending the after party, please use a designated parking area behind the Coldenham Fire Department on Manzari Drive. Follow Ridge Rd out of the forest, take an immediate left at the traffic light by the Citgo station, and you’ll find the fire department about 500 feet to your right. For those looking forward to some post-race gear, jersey options are available for pre-order with pick-up on race day or shipping. Place your order three weeks before August 1st to ensure a reduced price; otherwise, jerseys will be shipped after the event. Race Directors Ethan Kelly and Tim Schopen have crafted these courses to provide an unparalleled experience in Stewart’s natural beauty. Mark your calendars now for this epic two-day adventure!
