Have you noticed any of these signs at your favorite trailhead the past few weeks? The winter weather has done a number on our trails and MORE is actively working to prevent trail damage and educate trail users on riding in the winter and early spring season. Become an educated trail user – read the FAQs below and find more information on our webpage on MORE's Winter Riding Resources, including alternative ride options and resources to help you find out about real-time trail conditions. What is freeze thaw? When the temperature drops below freezing, the moisture in the ground freezes and because water expands as it freezes, the frozen soil gets broken up, resulting in less compaction of the trail surface. Once the air temperature rises above freezing, the newly broken up soil, in combination with the now melting ice, combine to make a muddy mess of the trail surface. These conditions are often worse where the sun warms up the trail during the day. As a general rule, if the temperature drops below freezing (32°F) for more than a couple of hours, a freeze-thaw cycle will occur. And once the melting starts, it will take several to many days for the trails to dry out following a freeze-thaw cycle or a winter rain event. How long depends on many factors, including air temperature, trail conditions, soil type, evapotranspiration rates, sun exposure, and others. When can I ride in the Winter? You can ride trails that are DRY or FROZEN. Depending on how cold it has been and how much rain or snow melt was recently added, it is usually okay to ride the trails if the air temperature is and has been well below freezing for several hours. For example, early in the morning after a night or more of below-freezing air temperature can yield a good, hard frozen trail surface; a “hard” freeze typically occurs with sustained temperatures of 28°F or lower. But it is important to plan your ride so that you are off the trail well before the melting begins. How do I know I shouldn’t be on the trails and why does it matter? Tracks on the Ground - Turn Around! Stay off the trails if you are leaving ruts in the trail. Riding in these conditions results in significant trail damage, and makes it take even longer for the trail to dry out. What about when the trails are 95% dry, but there is an occasional puddle due to a drainage issue? Remember the rule for the occasional puddle is to “ride through it” and keep single track single! Riding around the puddle only widens the trail and makes trail repair more difficult. Where can I find more information about trail conditions in my area? A great resource for the Montgomery County area is the Montgomery Parks Rain Out Line - Trails webpage, where real-time conditions for trails maintained by Montgomery County are updated regularly and up-to-date trail status is available for specific trail areas. Conditions on these trails are usually indicative of conditions for other nearby trails in Montgomery County, so if these trails are closed, other nearby trails are likley closed as well. A good resource in Virginia is the Fountainhead Facebook page and Park Hotline: Fountainhead Park FB Page: Fountainhead Facebook Page and Fountainhead Park Hotline: (703) 250-9124 Additional information on local trail rainout lines and local Facebook groups that often discuss local trail conditions can be found at MORE Trail Status Resources. Where else can I ride? Some Alternative Ride Suggestions are provided at MORE Alternative Ride Suggestions, including a great gravel ride resource at GravelMap Also, check out the 17-mile loop gravel/road ride in western Montgomery County, with stop descripions on the local history and geology available at MoCo Gravel Ride. Or, wait until spring and take the whole family!
