How It Works

We provide hard-driving original music, synced to your pace and built to burn calories. All of our songs are 30 minutes long and contain rhythmic and harmonic structure to help you stay focused during your run.

Original Music

Hella Sound running music is original compositions produced in-house by an ever-growing group of artists—no remixes or mash-ups here. This provides several advantages over typical running music mixes:

We’re not bound to the 3 minute mark. We’re not slaves to the 3 minute limitation imposed by the traditional radio/marketing-driven music industry. We can wind out for 30 minutes just like you do during your run.
We’re not limited to the verse-chorus-verse format. Most everything you have in your playlist has a relatively predictable progression through the song, where the artist tries to convey their idea within the framework of a “song”. We can use the longer format to our advantage and provide you with music that moves and builds outside of the radio-friendly format.
We don’t distort and ruin a good thing. You have music you love. Taking a song you know very well and speeding it up diminishes it—even cheapens it overall. Our music is designed to play at the fast paces that sync to running.

Synced to Your Pace

Most mass-market music clocks in at between 86 and 120 BPM. Your stride comes in between about 135 and 175 SPM. Finding a song that matches your pace is difficult. But we’re gonna change all that. With Hella Sound, each song is offered in preset rates (BPM) that will match your running strides per minute.

How Calorie Consumption is Calculated

Caloric consumption of physical activity is calculated using units of metabolic equivalent, or METs—1 MET being the baseline for caloric consumption of a person at complete rest. We base our calculations on 9 METs, the intensity of running slightly slower than 8 minute miles. We assume a person of 180lbs, but you can modify this to do your own calculation.
