Finding the best running shorts in 2026 isn't just about picking the right colour. The wrong pair can mean chafing by mile 3, a phone bouncing against your thigh, or a waistband that creeps down mid-stride. The right pair disappears — you stop thinking about your gear and start thinking about your run.
We've broken down the best running shorts for every type of runner, from daily trainers to marathon-day racers.
What Makes a Great Running Short in 2026?
Before diving into picks, here's what separates a good running short from a great one:
- Built-in liner — eliminates inner-thigh chafing without a separate compression layer
- Secure phone storage — a pocket that locks your phone flat against your body, not bouncing at your hip
- Ventilation — laser-cut perforations or mesh panels for heat escape during hard efforts
- Waistband stability — drawstring + elastic combo that stays put from start to finish
- Stride freedom — side slits or bound-edge hems that don't restrict your gait
Best Running Shorts for Daily Training
For everyday runs — whether that's a 5K before work or a long Sunday session — you need a short that handles everything without requiring you to layer up or strap on a belt.
The RUNNR 2-in-1 Running Shorts ($39) are built exactly for this. The built-in compression liner eliminates chafing entirely — fabric on fabric, not skin on fabric. Your phone sits in a thigh-level pocket inside the liner, flat against your leg, locked in. Keys and gels go in the zippered rear pocket. You put them on and forget about them.
What they replace: a running belt, a separate compression short, and a phone armband — all in one $39 garment.
Best for: Daily training runs, 5K–half marathon distances, runners who want to simplify their kit
Available in: Lime Green, Black, Electric Orange
Price: $39
Best Running Shorts for Race Day
Race day demands a different level of reliability. You need to know exactly where your phone is, your gels are accessible mid-stride, and nothing is going to shift or bounce over 26.2 miles.
The RUNNR 2-in-1 Marathon Shorts ($49) were designed specifically for this. The front mesh phone pocket sits right at the waistband — phone in, zip closed, done. You can check your pace or skip a track without reaching behind or breaking stride. The rear zip pocket holds gels, a soft flask, and race supplies simultaneously. The anti-chafe liner means you never have to think about coverage in wet conditions or full sprint.
Nearly 4 in 10 buyers come back and buy a second pair. That's the number that matters.
Best for: Marathon and half-marathon racing, long training runs, runners who carry nutrition
Available in: Black, Navy Blue, Grey Green
Price: $49
Best Running Shorts for Hot Weather
Summer running demands maximum airflow. Look for laser-perforation ventilation — precision-cut holes through the outer shell that allow direct airflow and heat escape during hard efforts. The RUNNR 2-in-1 Running Shorts feature this technology alongside bound-edge side slits for full stride freedom without the fabric rolling or fraying in the heat.
Best Running Shorts for Women
The same principles apply — liner coverage, secure storage, ventilation — but fit and coverage matter even more. Both the RUNNR 2-in-1 Running Shorts and Marathon Shorts include built-in liner coverage that eliminates the need for a separate layer underneath, making them a strong choice for women who want confidence in all conditions.

Frequently Asked Questions
What length running shorts are best?
Most runners prefer a 5–7 inch inseam for a balance of coverage and stride freedom. Shorter inseams (3–5 inch) suit speed work and hot weather; longer inseams (7+ inch) suit trail running and cooler conditions.
Do I need compression shorts under my running shorts?
Not if your shorts have a built-in liner. A quality 2-in-1 short like the RUNNR eliminates the need for a separate compression layer entirely — and removes the friction point that causes chafing.
Where should I carry my phone when running?
The best position is flat against your thigh (inside a liner pocket) or at the front waistband — both move with your body rather than bouncing against it. Armbands and rear pockets tend to shift and distract over longer distances.
Are 2-in-1 running shorts worth it?
Yes — if they replace a running belt, compression shorts, and phone armband, a $39–$49 2-in-1 short pays for itself immediately while simplifying your pre-run routine.
The Bottom Line
The best running shorts in 2026 are the ones you stop thinking about by mile 2. Whether you're training daily or toeing a marathon start line, the right pair handles your phone, eliminates chafing, and stays out of your way.
