The Story Behind LongRun and On-the-Go Garmin Charging

As endurance athletes and trail runners, we love our Garmin watches, but we all know the unspoken anxiety of watching the battery drop to five percent mid activity.
The market offers plenty of power banks, but nothing designed for the actual physics of moving. Taking your watch off to charge it means losing your GPS tracking and pacing metrics altogether, while trying to force a standard cable underneath your wrist ruins your running posture and risks damaging the charging port.
We built LongRun to solve exactly that by engineering an ultra light 19 gram external charging unit that clips securely onto your watch while it stays on your wrist, allowing you to keep tracking without limits.
It is important to note that Garmin's built in software automatically disables the watch's internal optical heart rate sensor whenever it detects an active power source, regardless of the charger you use. If heart rate tracking is required , the industry standard is to pair your Garmin with an external heart rate monitor, such as a chest strap . Your watch will perfectly record your external heart rate, GPS, and pace metrics all at once while LongRun powers up your battery in the background. 
We built this tool because we needed it out on the trails ourselves, and we refuse to let a battery limit our boundaries.
