My Favorite Running Shorts

I’ve been running for 25 years and have tried countless pairs of shorts—from trendy new releases to the classics everyone swears by. What I want for a 15-mile progression run is totally different from what I need for a quick 3-mile run before preschool pickup, but in general, these shorts are the ones I go back to over and over again, no matter what kind of run I’m on.

Whether you’re logging long runs, sprinting intervals, or just looking for something comfy for a walk or strength day, the right pair of running shorts can make a huge difference. Here’s a breakdown of my favorites based on comfort, performance, and personal trial-and-error.

My Favorite Running Shorts

My Everyday Favorite: Lululemon Speed Up Short

I reach for the Lululemon Speed Up Short most days—they’re that reliable. They’re slightly more fitted through the thigh than the Track That short, and they hug the booty in a flattering way. The waistband stays put, and they feel great on everything from tempo runs to recovery days. That said, they don’t offer much storage—no spot for a phone or more than a gel or two—so I usually reserve them for shorter runs or strength workouts.

I used to hate the 2.5″ Speed Up Short from Lululemon, but then I tried the Speed Ups with a 4″ inseam. If I had to pick only one pair of loose running shorts to keep, this is the pair. They’re cute and flattering, have a decent back pocket that doesn’t bounce, and feel like an appropriate length for a mom of two littles. I size up to a 6 in these.

Best Overall: Lululemon Fast & Free Shorts

The Lululemon Fast & Free shorts are my favorite for long runs or days when I want to carry fuel. They’re fitted but don’t have a built-in liner, so I wear a thong underneath—usually the Natori Bliss thong. The sleek Nulux fabric feels weightless and smooth, and I love the generous back pocket that holds my phone securely without bouncing. Plus, the side pockets are perfect for gels or keys. They’re pricey, but truly worth it. They used to make a few different lengths, and now all I can find is the 6″. If you prefer something shorter, I have some great alternatives below.

If you know you don’t like Lululemon shorts, try these Athleta Mesh Racer Run Shorts since they have a longer inseam but a slightly different fit.

Budget Pick: Colorfulkoala High-Waist Biker Shorts

If you’re looking for a Lululemon Fast and Free dupe, the Colorfulkoala biker shorts from Amazon come surprisingly close for a fraction of the price. The fabric is buttery soft with solid compression, and they stay in place even on long runs. They have deep side pockets but no back pocket, so they’re not ideal if you need to carry a phone. I wear thongs with these too, since they’re fitted and unlined. These are my personal favorite biker shorts for distance running.

I think the Amazon ones are more flattering and don’t ride up as much, but they don’t have the back pocket for my phone. But all things considered, I’m okay with that, especially given the cheaper price. I also own these in a light pink/tan color that I wear under short dresses, which might be my best “mom hack.” I wear a small size in these shorts; size up if you’re on the fence.

Bonus Budget Pick: Senita Rio Shorts

The Senita Rio Shorts are another great under-$30 pick, and I actually wore them during the Boston Marathon in 2018. They’re super compressive and high-rise, which I love for long runs. Just like the Colorfulkoala pair, they don’t have a back pocket, but they were still my top pick for race day (here are some tips for running faster if you’re in race mode) thanks to their fit and comfort. They aren’t as easy to buy as something from Amazon, but they’re totally worth ordering ahead.

Honorable Mention: Lululemon Track That Short 5″

If you’re not into tight shorts, the Lululemon Track That Short is your pair. The 5-inch inseam offers more coverage, and they’re roomy without being baggy. They still have a liner, stretchy waistband, and side pocket, but with a more relaxed fit overall. I wear these when I want something breezy, like for a hot recovery run or stroller walk.

Best Unlined: Rhoback Era High Rise Short

If you want an unlined short, the Rhoback Era High Rise Short is the best one I’ve found. They’re high-rise, very soft and breathable, and have a very flattering fit. I wear a thong underneath (again, the Natori Bliss thong is my go-to), and they work great for short runs or casual workouts. These feel like a blend of running shorts and lifestyle shorts, which I love.

Best Loose Short: Brooks Chaser Shorts

If you want something a bit more breezy than Lululemon or Athleta that still has a liner (vs. the unlined Rhoback), check out the Brooks Chaser Shorts. They have a looser cut through the leg and a soft liner. The waistband is flat and comfy, and they don’t ride up. They feel a bit heavier and like they have more fabric than Lululemon, but you may prefer that. So if you find Lululemon shorts don’t feel quite right, try the Chaser Shorts, which have a slightly longer inseam at 5″.

Know Which Fit and Length Works Best for You

Some runners prefer longer inseams to avoid chafing (I love a 5-inch short for running in the heat), while others like shorter or tighter fits for speed work. Fitted shorts are less likely to chafe between the legs for most people, especially on longer runs. Pay attention to how the liner feels too—some are more compressive, others more relaxed. And if you’re wearing unlined shorts or biker styles, you’ll probably want a thong underneath.

Prioritize Features Based on Your Intended Use

Think about what you need most:

• What are you training for? If you’re building up to a marathon, you’ll want shorts with enough storage for fuel. That’s exactly why I ran in the Senita Rios for Boston.
• Do you carry your phone? If yes, you’ll need a snug, secure back pocket or a running belt like the SPIbelt.
• What will you race in? Always train in the gear you plan to race in to test it out for comfort, chafing, and fit. See what to wear running here.
• Storage: Do you need room for keys, gels, or a phone?
• Liner Fit: Do you like a snug brief or more room? Or unlined?
• Compression vs. Airflow: Tight and supportive or loose and airy?
• Waistband Comfort: High rise or mid? With a drawstring?
• Fabric: Look for moisture-wicking materials like nylon, elastane, or quick-dry blends.

The best pair is the one you’ll want to wear again and again—so don’t be afraid to try a few and see what works best for your body and your mileage.
