Choosing Your Perfect Ultra Running Shorts: A Buyer’s Guide
Ultra running means long miles, tough trails, and pushing your limits. Your gear matters a lot, especially your shorts. Good shorts keep you comfortable for hours. Bad shorts can cause chafing and ruin your race. This guide helps you pick the best pair.
Key Features to Look For
When shopping for ultra running shorts, look for features that support long-distance comfort and performance.
1. Built-in Liner or Compression Layer
- Many ultra shorts come with a built-in brief or a separate compression liner.
- Liners prevent rubbing (chafing) between your thighs.
- Look for liners made of smooth, quick-drying material.
2. Storage Capacity and Placement
You need to carry fuel, a phone, and maybe a light jacket. Good storage is vital.
- Rear Pockets: Look for zippered pockets for keys or gels that won’t bounce.
- Stash Pockets: Many modern shorts have stretchy mesh pockets around the waistband or on the back that hold flasks or soft bottles securely.
- Phone Pockets: If you carry a phone, ensure the pocket is deep enough and placed where the phone won’t bounce against your hip.
3. Waistband Design
The waistband holds everything up without digging in.
- A wide, soft, and fully adjustable waistband is best.
- Drawstrings should be flat and easy to tie securely.
Important Materials for Long Runs
The fabric decides how well the shorts breathe and dry. Ultra running involves sweat and sometimes rain.
Lightweight Synthetic Fabrics
- Polyester and Nylon Blends: These are the standard choices. They wick sweat away from your skin quickly.
- Spandex/Elastane: A small amount of this material adds stretch. You need stretch for full range of motion when climbing or stepping high.
Moisture Management
The best shorts use fabrics labeled “moisture-wicking.” This means the material pulls sweat to the outer surface so it can evaporate fast. Dry fabric equals less chafing.
Factors That Improve or Reduce Quality
Small details often separate a great pair of shorts from a mediocre one.
Quality Boosters
- Flatlock Seams: These seams are sewn flat, so you do not feel bulky stitching rubbing against your skin. This significantly reduces chafing risk.
- Durable Water Repellent (DWR) Finish: Some shorts have a light coating that makes water bead up and roll off, which is useful in light rain.
- Reflective Elements: Small reflective logos help keep you safer if you run near roads in low light.
Quality Reducers
- Thick or Rough Stitching: Rough seams become painful irritants after 10 or 20 miles.
- Cotton Content: Avoid shorts with significant cotton. Cotton absorbs sweat and stays wet, leading to heavy shorts and serious chafing.
- Overly Tight Fit: Shorts that are too tight restrict blood flow and increase friction.
User Experience and Use Cases
How you use the shorts affects what features matter most.
Trail vs. Road Running
- Trail Runners: You need more durable fabric to resist snags from branches. Excellent pocket placement for easy access to nutrition is crucial.
- Road Runners: Lighter weight and maximum breathability are the top priorities since the terrain is smoother.
Weather Conditions
For hot, humid races, choose the lightest, most ventilated shorts available, often with split sides for maximum stride length. For cooler weather, consider 5-inch or 7-inch compression shorts worn under a lighter outer shell for extra warmth and support.
Ultra Running Shorts: 10 Frequently Asked Questions (FAQ)
Q: Should I wear underwear with ultra running shorts that have a liner?
A: No. The built-in liner acts as your underwear. Wearing separate underwear underneath usually causes extra seams and increases the risk of chafing.
Q: What is the best inseam length for ultra running?
A: Most ultra runners prefer shorter inseams, usually 3 to 5 inches. This length allows for a full range of motion and minimizes fabric rubbing against the thigh.
Q: How important is stretch in these shorts?
A: Stretch is very important. It allows your legs to move freely when climbing steep hills or taking large strides without the fabric pulling or restricting you.
Q: What does “chafing” mean, and how do the shorts help prevent it?
A: Chafing is painful skin irritation caused by repeated rubbing. Good ultra shorts prevent this using smooth, moisture-wicking liners and flatlock seams that do not rub.
Q: Are waterproof shorts good for ultras?
A: Generally, no. While waterproof fabric keeps rain out, it traps sweat in. Most ultra runners choose highly breathable, quick-drying fabrics instead.
Q: How many pockets do I really need?
A: It depends on your race plan. For longer races (50k+), you need at least three secure spots: one for keys/phone and two for easily accessible gels or nutrition.
Q: Should I size up for ultras?
A: You should buy the size that fits correctly according to the brand’s chart. If you are between sizes, size down slightly for compression, but never size up so much that the waistband slips down.
Q: Are compression shorts better than split-leg shorts?
A: Neither is strictly better. Compression shorts offer excellent muscle support and chafe prevention. Split-leg shorts offer maximum airflow and stride freedom. Many runners wear compression shorts *under* a very light split-leg shell.
Q: How often should I wash my ultra running shorts?
A: Always wash them after every single use. Sweat and salt build-up degrade the technical fabric quickly and increase the chance of bacteria causing skin issues.
Q: Can I use anti-chafing balm with these shorts?
A: Yes. Even the best shorts benefit from anti-chafing balm (like Vaseline or specialized sticks) applied to high-friction areas like the inner thighs, especially on very long, hot days.
