About
Old Man Winter is an endurance event in Lyons, Colorado, on February 7, 2027, combining running and gravel riding over mixed terrain: gravel, snow, climbs and narrow trails. The running program includes a 10K (6.2 miles) at 10:00 a.m. and a 5K (3.1 miles) at 10:30 a.m., while the rides cover 75 miles at 9:00 a.m., 40 miles at noon and 23 miles at 12:30 p.m. Entry includes custom gear, a neck gaiter, a training plan and a bib with coupons, plus access to online contests. Aid stations serve food and drink along the route, and a post-race party offers a hot meal and drinks. Prizes include snowflake awards and a purse for the top finishers in each category.
Winter terrain is the whole point here, so train the way you will race: run some of your weekly mileage on snow-packed or gravel roads and get comfortable with shorter, quicker steps on loose ground. Screw-in studs or trail shoes with real lugs are worth the trouble.
