What to Look for in Running Pants for Marathon Performance

Fit That Goes the Distance

Fit is everything when choosing running pants for marathon distances. Ill-fitting pants cause chafing, rubbing and bunching, issues that become painful over 42.2 km.

Look for:

• Elastane/spandex blends for ample stretch

• Tapered joggers or tights that minimise drag

• Flat seams to prevent friction

• Supportive waistbands that stay put without digging in

Many comfortable running pants also feature reflective accents for early-morning or late-evening training, a small detail that dramatically boosts safety.

Climate-Ready Fabrics for Any Marathon Weather

The weather on race day is always unpredictable, so the best long-distance running pants excel in both breathability and temperature regulation. Knowing how totransition between seasons supports top performance. 

For warm weather:

• Quick-dry, lightweight fabrics

• Mesh ventilation panels

• Streamlined cuts that reduce heat build-up

For cold weather:

• Thermal or fleece-lined interiors

• Wind-resistant materials

• Tapered legs to lock in warmth

Extras like ankle zippers add versatility, making it easy to remove pants over shoes at the start line or adjust ventilation during warm-ups.

Storage & Functionality for Race-Day Essentials

Functionality matters as much as comfort when deciding what to wear for a marathon. You need storage that won’t bounce or get in your way.

Look for:

• Zippered pockets for gels, keys or cards

• Secure side pockets for easy-access fuelling

• Adjustable waist cords for a customised fit

Brands available at The Athlete’s Foot, including ASICS, design marathon running pants with exactly these performance-focused details in mind.

FAQ: Running Pants for Marathon Training

What are the best running pants for marathon distances?

The best marathon running pants offer sweat-wicking fabric, supportive stretch, and a secure fit that reduces chafing. Tights or tapered joggers are ideal because they minimise drag and allow natural movement over long distances.

Should I wear tights or joggers for a marathon?

Both work well, but running tights are generally preferred for long-distance events because they offer better muscle support and reduce friction. Tapered joggers are great for training runs or colder conditions. Learn more about the difference by reading:Should Running Pants Be Loose or Tight?

What fabrics should I choose for marathon running pants?

Look for technical materials like polyester blends with elastane. These fabrics provide moisture-wicking performance, temperature control and stretch, essential for long-distance comfort.

Can I wear running pants in hot weather?

Yes. Many long-distance running pants are designed with lightweight, breathable fabrics and mesh ventilation. Choose quick-dry pants or pair shorts with performance briefs for very warm temperatures.

What should I wear under my marathon running pants?

Performance briefs or half tights help reduce friction and provide added support. Avoid cotton, as it traps moisture and may cause chafing during long runs.

How should marathon running pants fit?

They should feel snug but not restrictive. Look for a secure waistband, flat seams and stretch throughout the legs. A good pair should stay in place without bunching or slipping.

Do I need pockets in my marathon pants?

Opt for marathon running pants with zippered or hidden pockets if you plan to carry gels, keys or a card. Storage is especially helpful on long training runs.

Are compressed running pants better for marathons?

Compression-style tights can offer extra muscle support and may reduce fatigue. While not essential, many runners prefer them for long races because they minimise movement and improve comfort.
