A Guide to Running Through Mud

Running through mud is part of life on UK trails from October to March. Wet weather turns fields, woodland paths and bridleways into slippery, sticky ground that tests your grip, balance and patience. The good news is that muddy trail running gets far easier with the right trail running shoes, sensible kit and a few simple technique changes.

• Best shoes for mud: The best shoes for running through mud have deep, widely spaced lugs (the raised studs on the sole) of roughly 6mm to 10mm.
• Gore-Tex or not: Gore-Tex trail shoes suit cold, wet days with shallow puddles, while non-waterproof shoes drain faster in deep mud and water crossings.
• Technique: Shorter strides, a quicker cadence and a straight line through puddles reduce slipping.
• Clothing: Running tights, a waterproof jacket and close-fitting trail socks keep your legs warm and your skin protected on wet trails.
• Safety: Avoid bogs, check puddle depth before you commit, and carry a phone and head torch on remote routes.

Grip decides how a muddy run feels. Road shoes have smooth, shallow tread built for pavement, so road shoes clog and skid on soft ground. Trail running shoes use deeper lugs, softer rubber and open tread patterns that bite into wet soil and shed mud as you run.

Lugs are the raised studs on the outsole, which is the bottom of your shoe. Deeper lugs dig into soft ground in the same way that studs grip on a football pitch. Use this table to match lug depth to your terrain.

Softer rubber grips wet rocks and roots better but wears faster. Firmer rubber lasts longer on dry, rocky trails. Widely spaced lugs stop mud packing between the studs, which keeps the grip working for the whole run.

A flexible sole also helps. A sole that bends with your foot releases mud on every step and prevents 'mud on mud' slipping, which happens when a clogged sole slides over wet ground.

Mountain and fell runners usually choose the deepest lugs, because steep, wet ground punishes shallow tread. Beginner trail explorers and half-marathon improvers who run park paths and bridleways often prefer moderate lugs. Commuter runners who mix pavement and dirt do best with shallower, road-to-trail tread.

Gore-Tex trail shoes suit cold, wet days with surface water, but non-waterproof shoes usually work better in deep mud and water crossings. Gore-Tex is a waterproof, breathable membrane, which is a thin layer built into the shoe that blocks water from entering.

Waterproof shoes protect your feet from rain, wet grass and shallow puddles. Waterproof shoes keep feet warm in winter, and they work well on snowy or frosty trails. They are a sensible choice for steady, cold, wet runs where splashes are the main problem.

Water that spills over the ankle collar cannot escape a waterproof shoe, so your feet stay soaked for the rest of the run. Waterproof shoes also breathe less, so feet can overheat and sweat in milder weather. A soaked pair of Gore-Tex shoes dries more slowly than a standard mesh trail shoe.

Choose waterproof trail shoes for cold, wet weather with shallow puddles. Choose quick-draining, non-waterproof shoes if your route includes deep mud, streams or frequent full soakings. Add waterproof socks for warmth when your feet will get wet anyway. Browse waterproof running shoes to compare options.

Cold, wet legs stiffen up and react slowly, which raises the risk of a slip or a strain. Warm muscles respond faster on unpredictable ground, so the right clothing protects your performance as well as your comfort.

Muddy running rewards smooth, nimble footwork more than raw strength. These four habits make the biggest difference.

Think of mud as thin ice or water that you want to cross quickly. The less time your foot stays planted, the less you sink. Move quickly from one foot to the other, use small steps or a light hop to shift your weight, and keep your upper body loose and relaxed.

Changing speed and direction at the same moment is the most common cause of a muddy slide. Mud cuts traction, so a sudden turn while braking or accelerating pushes your lugs past their grip limit. Follow these steps instead:

1. Look ahead and spot bends and obstacles early.
2. Slow down on the straight section before the turn.
3. Turn at a steady, controlled pace.
4. Speed up again once you are running straight.

Cadence is the number of steps you take per minute. Shorter strides keep your feet under your body, which lowers your centre of gravity and gives you more control. Quick, light steps help you react to changing ground. Keep your torso upright and use your arms for balance around corners.

The edges of puddles and muddy paths are usually the slickest and most unstable parts, and edges can also cause twisted ankles. Running through the middle keeps your stride natural and your balance steady. Pick a line, commit to the line, and keep moving, because hesitating in deep mud makes you sink.

Not every puddle is shallow and not every muddy stretch is safe. A little caution saves soggy socks, twisted ankles and long walks home.

Trail running poles give you extra points of contact with slippery ground. Poles take load off your legs, help you hold a steady rhythm and make muddy climbs easier. Poles also work as a depth gauge, so you can test a puddle or boggy patch before you step in.

Keep your hands out of the straps on risky, slippery terrain. A free hand lets you drop the poles in a fall, which protects your wrists. Plant each pole firmly and test the ground before you shift your weight.

Quiet trails stay firmer after rain. Heavy traffic compacts the ground and breaks up plant roots, which lets water pool and mud form. Bridleways and byways take horses, bikes and sometimes vehicles, so bridleways and byways rut up quickly in wet weather. Footpaths see fewer users and usually hold up better.

• Use OS Maps or Komoot to find quieter footpaths away from main bridleways.
• Ask local run clubs and walking groups for drier winter routes.
• Expect shaded, north-facing sections to stay damp longest, and choose your line to match.

Carry a compass or a GPS sports watch to keep track of your direction on unfamiliar ground.

Yes, running through mud gives you a strong full-body workout. Uneven, slippery ground makes your core, glutes and stabiliser muscles work harder on every step. Soft ground also feels kinder underfoot than tarmac. Reacting to slips builds balance, agility and mental toughness that carry over to every race.

Build up gradually if you are new to mud. Your calves and ankles work harder on soft ground, so start with shorter runs and add distance over a few weeks.

Cleaning your shoes soon after a run protects the grip and the fit. Knock off loose mud first. Rinse the shoes with lukewarm water and a soft brush, and take out the insoles. Stuff the shoes with newspaper and leave them to dry away from radiators, because direct heat can weaken glue and warp foam. Our trail running kit care guide covers shoes, jackets and socks in more detail.

Grip, warmth and smart footwork make muddy trails fun instead of frustrating. Deep, widely spaced lugs keep you upright, and the right choice between waterproof and quick-draining shoes keeps your feet working. Shorter strides, a straight line and a careful eye for hidden depths keep you safe. A warm, dry kit and a quiet route finish the job.
