How muddy is too muddy?
Nobody’s ever been able to give me an answer that seemed reasonable to this question, but you know this kind of thing, so maybe you can weigh in: When is it ok to ride a wet trail?
Back in high school, we used to rip it up in waist-deep mud just to see how dirty we could get. It never even occurred to us that the scars and ruts we left on the wet trails would be there for months. Now that I’m a little more “enlightened,” I’m never sure how long I should wait after rain before I hit the trails. How damaging is it to ride a wet trail? Do we need to wait until it’s dry enough that our tires won’t leave a rut? The NorCal rainy season is upon us and I can’t take it anymore — I want to get out and ride… but I don’t want to ruin my favorite spots.
What do you think!?
Curtis Keene rips ultra sweetness in Santa Cruz. The redwood forests are prime when wet.
I spent 10 glorious years in NorCal, so I know your mud brother, I know your mud.
Do not ride if:
1) The mud sticks to your bike, and/or
2) You leave tracks.
If mud sticks to your bike, you are leaving ruts behind. If you leave ruts behind, that tells everyone a renegade mountain biker came through, plus it speeds erosion.
Whether these bad things happen depends on the trail’s surface and layout. In general:
– Clay is bad news. Wet clay is very slick. Moist clay is very sticky. Not cool. East Bay.
– Loam, aka topsoil, is good news. It drains very well and encourages the growth of forest pixies. Santa Cruz.
– Rock and gravel tend to be good. Upper Montara Mountain.
– Steep trails tend to drain the best, if they’re built correctly. El Corte de Madera.
– Flat trails tend to accumulate silt and get mucky. The rolling hills in the East Bay.
– Frozen trails are very ridable. Until they thaw.
This river bed in Left Hand Canyon OHV Area sure is wet, but I’m not doing any damage.
And while we’re on the subject:
– Good Bay Area spots for rainy weather: almost anywhere in the coastal mountains; Rockville; Upper Montara Mountain; Stevens Canyon; Mitchell Canyon on Mount Diablo; parts of Henry Coe State Park. If you’re not leaving tracks, you’re good.
– Do not ride around puddles. This widens the trail and degrades habitat that will someday support a condominium development. Ride through the puddle. Keep the trail the width it is.
– Do not transport dirt/mud from place to place. As you might know, the East Bay is rife with star thistle. Clean your bike before you ride elsewhere. If you bring star thistle to Boulder, CO I will have to kill you.
Please, for this snowbound and injured Coloradan, go rip some Santa Cruz love.
My two cents on NorCal trails that are good in the wet: Oat Hill in Calistoga is very rocky, the rain only makes the rock super slippery and harder to clean. Los Posados State Forest at Angwin (warning: legality/local rights/closedness debatable) is gravel. Most of Boggs Mountain is gravel (but stay away from some of those super-steep trails – and gunfire). After riding any of these in the rain I am wet and spattered, but not muddy. As a long-time trail builder I am careful not to wreck trails. But the moment I am mostly training on the road.
“…the rain only makes the rock super slippery and harder to clean…”
– What? So the rock gets so slippery that you fall on them, leak certain bodily fluids on them and then it’s harder to clean the blood stains off of them again? 😉
Fort Ord (aka Sea Otter) in Monterey is primo when it rains. Most of the ground is hardpacked sand and sandstone, and it’s actually easier to ride there when it’s a little wet. Not as technical as Santa Cruz or the rocky stuff further north, but it’s fast and fun.
Trials along ridge lines drain really quickly so if there are any in your area that can be an option too.
