Why You Shouldn’t Ride Muddy Trails 

If you’ve ever shown up after a rainy night and thought, “It’s just a little wet—I’ll be fine,” you’re not alone. But for natural-surface trails, muddy conditions aren’t just a comfort issue—they’re a trail damage issue. 

Choosing not to ride when trails are muddy is one of the simplest ways you can protect the trails we all love, reduce volunteer workload, and keep systems open and enjoyable longer. 

Wet trails are fragile 

Even well-built trails rely on the tread staying firm and the drainage working as designed. When the ground is saturated, it loses strength—meaning tires and footsteps can permanently change the trail surface in just a few passes. 

Mud turns into damage fast 

When you ride on a muddy trail, your tires can: 

  • Cut ruts into the tread 
  • Create depressions that hold water 
  • Widen the trail as riders detour around mudholes 
  • Break down drainage by pushing soil into low spots and drains 

Those ruts and pockets don’t just “dry out.” They become water collectors. Once water is trapped, the trail stays wet longer, the mudhole grows, and the damage spreads. 

One bad day can mean weeks of problems 

A muddy trail might look rideable in the moment, but the impacts can last a long time. Ruts harden into uneven tread, puddles become recurring features, and riders keep widening the trail to avoid the mess. Sometimes the trail won’t truly recover until sustained dry weather returns. 

Riding muddy trails steals time from improving trails 

Every muddy rut and expanding mudhole eventually has to be repaired: 

  • Reshaping the tread and restoring the trail “crown” 
  • Rebuilding drainage so water can shed again 
  • Hauling rock or materials for armoring 
  • Repairing widened “braided” sections back into a single line 

That work takes significant volunteer time and materials—time that could otherwise go toward new trail, better flow, and long-term improvements. 

What you can do instead 

When trails are wet: 

  • Check trail status/condition updates before you head out 
  • Choose activities that don’t damage soft ground (fitness rides on durable surfaces, indoor training, etc.) 
  • Wait for the trail to firm up—often a day or two can make a huge difference 
  • If you’re unsure, err on the side of protecting the trails 

A good rule of thumb: if you’re leaving tracks or spraying mud, it’s too wet. 

The bottom line 

Not riding muddy trails is trail stewardship in its simplest form. It protects the work already done, reduces repairs, and helps keep trails open and fun for everyone. 

Thanks for doing your part—your decision makes a real difference for every rider who comes after you.

Trail Conditions

Natural surface trails and bike parks can be easily damaged when they’re soft, wet and/or muddy.  All trail users should stay off the singletrack trails and jump lines unless they’re dry, or frozen solid.  CAMBr volunteers put in many thousands of hours each year maintaining and constructing trails, and we closely monitor their condition.  

CAMBr uses the Trailbot smartphone app to publish trail conditions updates.  Trailbot is a completely free, ad-free, easy-to-use trail conditions app for iOS and Android  – so you’ll know what to expect before you go, and can make informed decisions when conditions aren’t favorable for hitting the singletrack.  

Visit Trailbot.com to download the app, or find it in the Apple App Store or Google Play Store. Within the app you’ll find not only current trail conditions updates for all your favorite CAMBr trails, but also weather information, trail descriptions, maps, and other useful links. Trailbot updates are also pushed to our website for easy access.

Please respect the trails, and all the work that goes into them, by staying off when they’re soft.

ABOVE ALL – IF YOU’RE LEAVING AN IMPRINT, IT’S TIME TO LEAVE

WHAT ARE FREEZE/THAW RULES?

There’s a season in the Chicago area, typically between mid-November and the end of March, when temperatures will drop below freezing at night and then warm up above freezing during the day. What this means for the trails is when actually frozen they are hard and good to ride. But when the temps go up and the moisture in the ground thaws, the dirt becomes very soft and muddy. This is because the water in the soil expands when frozen and it looses the tightly packed soil. The result is the trails can become very soft and muddy even if there hasn’t been much rain or snow fall.

So, to protect the trails from damage, only ride when the ground is frozen hard, and get off once the ground begins to warm up. South facing trails will usually soften up first, and if the sun it out and the temps get into the 30’s, you’ll probably need to be done by 10AM.

Remember, if you’re tires are leaving an imprint, it’s too soft to ride.
