JORBA PSA: As winter settles into New Jersey, our trails face one of their biggest threats: the Freeze-Thaw Cycle. We know the itch to ride doesn’t stop when the temperature drops, but riding at the wrong time during these months can cause permanent damage to the trail systems we work so hard to build and maintain.
❄️ What is the “Freeze-Thaw” Cycle?
During the winter, moisture in the ground freezes overnight, expanding the soil. When the sun comes out and temperatures rise above freezing during the day, that top layer of soil melts and turns into a fragile, peanut-butter-like grease on top of a frozen base.
This is the danger zone.
🚨 Why It Matters
Riding muddy trails during a thaw isn’t just messy for your bike; it destroys the trails.
-
Rutting: Tires cut deep grooves into the soft soil. When these freeze again overnight, they become permanent, hardened hazards that channel water and erode the trail.
-
Widening: To avoid the mud, riders often go off-trail around the wet spots. This widens the singletrack and kills surrounding vegetation (a phenomenon known as “trail braiding”).
-
Maintenance Nightmare: It takes volunteers hundreds of hours to repair damage that can be done in a single afternoon ride.
✅ The Golden Rule: Ride Dirt, Not Mud
You can still ride in winter! You just have to be strategic about when.
- Choose your Park Wisely when Temperatures are Variable: Some trails/soils/parks handle moisture better than others. The rockier/sandier the better when the thermometer dips above and below freezing erratically.
-
Ride Early: The best time to ride is typically early in the morning when the ground is still frozen solid.
-
Check the Thermometer: If the temp is rising above freezing (32°F / 0°C), try to finish your ride before the ground softens.
-
The “Track” Test: Look behind you. If you are leaving a visible rut or tire track in the soil, please stop. Turn around and ride the road back to your car.
“If you’re leaving tracks, turn back.”
