Frequently Asked Questions
What fits inside?
Your phone, a key, cards, and a gel. Tempo is built around the essentials loadout: everything you actually need on a lighter carry day, secured in its own place.
How is Tempo different from the Endorphin Belt?
They are two different tools built to the same zero-bounce standard. The Endorphin Belt is our full-capability system with hydration, fuel storage, and organized carry for long runs and race day. Tempo is our streamlined system for the days you only need the essentials. Many athletes own both and choose based on the session.
Will it bounce when I pick up the pace?
No. Tempo is built to the same zero-bounce fit standard as everything we make, and it is covered by our No-Bounce Guarantee. It was designed specifically for the sessions where pace is the point.
Is the phone pocket sweatproof?
Our phone pocket is protected from sweat and moisture encountered during running, but is not meant to be submerged.
How does sizing work?
The Endorphin Belt Tempo uses our proprietary dual adjustment for a secure fit accommodating 18-40” waist sizes.
What’s your return policy?
We are confident you will love it, and offer a no-questions asked 30 day return policy. If you don't like it for any reason, let us know and we will work to make it right.
Customer Reviews
The tempo belt is perfect for those shorter runs when I only need my phone, a gel, and my car keys. It remains lightweight, comfortable, just like the original belt it doesn’t bounce around!! With this belt. I can finally stop hiding my car keys on my tire at the track 😂
I’ve used Endorphin belt for every training and race for over a year and love the quality of the belt and literally doesn’t bounce! The new Tempo belt is effective for track workouts and speed without compromising the quality of the belt. Game changer!
