Summer Running

There's nothing quite like interrupting an easy summer run to jump in a body of water. But in our experience, the aftermath is a drag (literally). Wet running shorts are a soggy mess, while swimsuits are too stiff to comfortably run in. The Run Cannonball Run is our solution: swim-friendly running shorts, designed to get you to the water’s edge with speed and comfort, while performing like a swimsuit when you hit the water.

Rio is 6'1" and wears a size Medium.

Splash Away

Regular running shorts aren’t cut out for a swim (you’ll chafe all the way home). And swim trunks aren’t made for running (you'll chafe all the time). The Run Cannonball Run is made for both. Made from an Italian swim fabric previously used for Olympic Speed suits, its four-way stretch shell is moisture-wicking, quick-drying and cool to the touch.

On The Line

The key to a successful run cannonball run is a liner that can dry in a snap, this year’s update features a lighter weight version of the swim-fabric used in the shell.

Store & Go

The Run Cannonball Run Shorts feature two hand pockets and one internal zip pocket for storing a key or credit card for post-run beers. Don't forget to take out your phone before leaping.

To The Water
We Go

Workouts can wait. When the sun’s shining and the mercury is heading toward triple digits, tear up your training plan and take your legs on an adventure. There are no rules or regulations; the only goal is to find the best body of water for submerging yourself mid-run. Maybe that means executing a perfect cannonball off a rock or ducking into chilly waves. However you do it, this is what summer is all about. Make a splash: run, cannonball, run.

Rio Lakeshore took the new Run Cannonball Run shorts for a spin at a swimming hole near Santa Barbara. Like all the best run cannonball run destinations, it's a little hard to find.
