Running Shorts
The Interval 5-inch running short is Ninja Run Club's training short: a lightweight woven shell with an internal brief, a zip pocket that holds a key and a gel, and the NR mark at the hem. True to size, ships from Dallas, 30-day returns.
Five inches is the working inseam - short enough to move freely on track Tuesday, long enough that you will happily stand in the coffee line after. The Interval short keeps decisions to a minimum: the internal brief is built in, the zip pocket secures the essentials, and the shell is light enough to forget.
Pair with the Route Line singlet for race-day kit or the Mile Marker crew socks for daily training. No chafe, no drama.
Frequently asked questions
Do the shorts have a liner?
Yes - an internal brief liner is built in, so they are ready to run as-is.
What fits in the zip pocket?
A key and a gel, secured through a full session. Larger phones ride better in a vest or belt.
Is 5 inches a good running shorts length?
It is the classic training length - free enough for speed work, covered enough for everything else.
