If you’re a mountain biker, you are very likely to race in the mud if you haven’t already, which can mean equipment failures and cold race conditions. And as this year’s Dirty Kanza proved, mud isn’t just limited to fat tire escapades.

Click through for three key tips to help minimize the common pitfalls racers may encounter during their spring racing campaign…

Know your conditions

If you’re planning to race in an area that’s far away or has different weather patterns from what you’re used to, make sure to contact a local shop (or race promoter) for current and race day trail conditions. If it has been or will be raining, try to get an idea of the soil conditions. Clay-based soils tend to build up on tires, pedals, and every other critical bike part. Rockier soils tend to drain well, so racing in the rain will most likely just be wet.

Tweak your equipment

For a key race in muddy conditions, I like to make a few equipment changes.

Tires: Skinnier mountain bike tires with tall, widely spaced knobs offer more clearance for sticky mud. They roll slowly and will offer poor traction in most other conditions, though, so don’t leave them on post race.

Fender: Yes, I know, it’s a bike race, not a commute to the movies. But front fenders keep mud from flying into your face, glasses, and eyes, which means you’ll be able to see, and being able to see means riding faster! In a pinch a tall water bottle can be zip-tied to the down tube. Another neat trick is to cut an inner tube and then stretch and zip tie it from the fork’s crown to it’s arch. This will keep mud from flinging forward into your path, which has an uncanny way of finding your eyes.

Brake pads: For disc brakes I like to switch from an organic pad to a metallic pad. It’s possible to wear out a set of organic pads in a single muddy race. Metallic pads offer better braking power in poor conditions and will last significantly longer. The down side? Metallic pads can howl, so be ready for noise.

Cables and housing: While offering a little more friction than new, clean cables, a solid housing from shifter to derailleur will offer better shifting performance on longer wet races. Remember, a drivetrain is compromised in muddy conditions. Shifting under load is a bad idea unless you want to risk a broken chain, chain suck, or other common “mud mechanicals” like a completely wrecked rear derailleur.

Replacement derailleur hanger: No, it’s not really an equipment choice, but always have one in your race bag, especially for multi-day mountain bike races or cross weekends. This is probably the smallest, cheapest, and easiest to carry part that you will never find when you need it.

Chain lube: Leave your dad’s WD-40 at home and throw a wet lube in your bag. Wet lubes are messy and will attract more dirt and grime than a dry lube (which means don’t use them in dry, dusty conditions), but they stay on longer when it’s nasty out. I’ve had great luck with Gnar Lube’s Blue Opal lube.

Pick your clothing wisely

Picking the right clothing for wet racing is tricky. Remember, you’ll produce significantly more heat when racing than when training, so I prefer the “less is more” adage. If it’s wet I tend to use an embrocation or petroleum based oil to repel water instead of arm or leg warmers. In my experience, more clothing often means more wet clothing, which gets heavy in a hurry. Clothing is very personal, however; I know a seasoned pro who knowingly starts races overdressed because he hates being cold. Before deciding what to wear, consider the terrain, time of day, race length, remoteness, etc. Always err on the side of caution. Always.

Speaking of caution, even if you’re not usually one to wear eye protection (i.e. sunglasses) while riding, a good set of clear or yellow lenses will keep the inevitable mud and spray from blinding you.

Remember, mechanicals are more likely to occur in muddy conditions. A little bit of clothing and equipment preparation will help minimize some common muddy racing dilemmas and give you a leg up on your competition. Have fun and enjoy the slop; the dusty season is just around the corner!

  1. One thing that isn’t mentioned but is a life saver is a cycling cap under the helmet. You can put your brim down, and put your glasses at the end of your nose. The glasses will shield your eyes from incoming spray/mud from below while the cap shields them from above. You end up having a small slit where neither the cap or glasses cover but if you have the positioning right, nothing will go in your eye.

  2. I bring an old pair of shoes to warm up in and change for the race. Also saves me from the headache of cleaning out the lugs and cleat right before the start.

    Parking lots at races are often muddy. I have a sport kilt (a fancy towel with a velcro waist) for changing in public. But standing on top of your shoes to keep out of the mud is asking to show off your kibbles and bits to everyone nearby. I bring a rubbermaid storage bin lid (25gal) to stand on under the rear hatch. The lid has a raised outer rim so it keeps out water, they are pretty indestructible and easy to get at Lowes or Home Depot.

  3. Yes second the cap, it’s the best addition ever to foul condition riding!
    Lightweight Windstopper gilet are great too, they absorb hardly any water and keep the kind off a damp body, but don’t keep you too warm.

  4. Here’s a top four muddy racing in clay soils : don’t do it!!! I have twice destroyed drivetrains and brakes racing in wet clay filled soils. Absolute loss of brake power is dangerous and replacing every moving part on the bike except wheels is way too expensive. I will never make that mistake again.

    The first time that happened was a learning experience. The second time I was committed to a big end of season race that all my friends were doing and I had trained hard for (Iceman). In the end, I greatly regretted it. The clay mud kept building up on my chain and narrow ride ring so bad that the chain would just get pushed up and over the teeth. I would have to pound the chain with my fist to get it to sit back down on the teeth. When that happens every half mile, there’s no point in racing or riding. It’s bad for the trails too (this race was mostly on logging roads, so not a concern).

  5. Another Iceman racer! Yeah, last year was muddy. Heard of many guys who did $200 – $400 damage on brakes and drivetrains. I was able to rent a bike and spare myself that agony.
    Good idea on a fender. I’ve spent many miles trying to wink sand out of my eye that got past my glasses.

  6. I was also at Iceman (mudman) and agree that this race has pretty much made me “not” race when it’s raining and muddy anymore. this was actually the 3rd race I’ve done where it was so muddy I lost my brakes by the end and you’d think I’d learn. I’m an amateur, I don’t get paid but it isn’t that fun and you just end up replacing a lot of parts at the end. I did way more than $400 in damage but to be fair my drivetrain was going to be replaced at the end of the season anyway but those 30 miles felt more like a couple thousand with constant sand grinding the entire way.

    Unless you get paid to be there or someone is picking up your bike tap it just isn’t worth it (to me anyway).
