Description
RUNNR Marathon Shorts — Front Mesh Phone Pocket · Rear Zip Supply Pocket · Anti-Chafe Liner
Race day is not the time to figure out where your phone goes.
Most runners show up with an armband they hate, a belt that bounces, or a rear pocket they can't reach mid-stride. They spend the first kilometre adjusting and the last kilometre regretting.
These shorts were built so none of that happens.
The front elastic mesh pocket sits right at the front waistband — phone in, zip closed, done. You can glance at your GPS, check your pace, or skip a track without twisting, reaching behind, or breaking your stride. The front position is actually the best place to carry a phone during a run — it moves with your core, not against it.
The rear zip pocket handles everything else. Soft flask. Energy gels. Cards. Race supplies. All loaded in simultaneously — and the zip stays closed from the start line to the finish. No belt. No vest. No separate carry system.
The built-in brief liner gives you extra coverage, so you don’t have to worry about the shorts becoming see-through in wet conditions, bright light, or full movement. It’s built in. It’s handled.
And the double-layer construction gives you the coverage of two garments in one — outer shell, Build in liner, complete kit. You show up to the start line with fewer things to manage and more focus on the race itself.
Nearly 4 in 10 buyers come back and buy another pair. That's the number that matters.
What’s in it:
Front mesh phone pocket — easy access mid-run, stable and bounce-free
Secure back zip pocket — holds gels, flask, and essentials safely
Adjustable drawstring waistband — secure fit from start to finish
Lightweight performance fabric — breathable and built for distance

I used these in a 5k race had my phone and car key. I'm looking forward to using them in my next half-marathon. I've trained long runs with these holding phone and 6 gels they are fantastic very minimal bounce. I highly recommend them. 👌
It is a good running shorts. Soft and breathable. Quality is good. Built-in belt is helpful though not so snug so i have to tighten it. Size runs small so I sized up. I am 5'4" 62Kg. I usually wear Medium with 32" waist but I sized up to Large as advised. Thank you
Nice fitting, comfortable, phone pocket in back of shorts big enough for my phone which is a 17 max pro so quite big. Will be ordering more in future 👌🏻
Absolutely love these. Perfect for easy runs and long runs alike - I forget that my phone's in the thigh pocket and the back pocket can fit all the gels you'll need! Complete game changer for my training! Would recommend going down a size as they come up a bit big - not massive but I'd have preferred a bit more snug.
I wore my new 2 in 1 running shorts during my first 100 mile event at the Northburn 100 in New Zealand last weekend. The shorts were very comfortable and stayed the distance for the 40 hours it took to complete.
I really like the side pockets for easy access of a kerchief and for stowing wrappers and rubbish on the run.
The phone pocket in the liner was convenient but I found the stretchy fabric was very ‘grippy’ when trying to stow the phone after taking a photo. It was just a bit of a fiddle to have to stop and muck about to put my phone away.
Otherwise the shorts are great value.
Great shorts! Perfect for all distances, I've done four marathons and two half marathons wearing them - Zero Chafe, super comfortable and plenty of storage. Highly recommend!
Just ran 115miles down the Fife Coastal Path, Scotland. The weather was crazy with the gale force headwinds and freezing rain after halfway. Wore Runnr 2in1 shorts all the way and even in a downpour they performed brilliantly. Zero chafing and functioned well when completely wet.
