Random reboots during interval transitions
-
Hi everyone,
I’ve had my Suunto Run for about a year now. Today I experienced a frustrating issue during a high-intensity interval session (3x2000m).
Right at the end of the first 2K block, exactly at the millisecond the watch was transitioning from the interval to the recovery phase, it froze and rebooted itself. This isn’t the first time it has happened—it has occurred about 3 times over the past year—but today it completely corrupted the .FIT file (merging laps and losing pace data). -
hello @braisfb , same with V1. Very frustrating for me, the 2 times it happened, both during a race. There is a thread to cover theses crashes : https://forum.suunto.com/topic/15153/crash-reports-collection-q1-2026?_=1783714628703

My watch has reset three times so far in training. Now I’m nervous at every training session.

Good morning ,
I would like to provide an update and share more details regarding my previous post about the random reboots.
Today, 19/07/2026 (two weeks after the first incident), my Suunto Run rebooted again right in the middle of an outdoor running workout.
I want to highlight an important detail that might help narrow down the issue: during the week, I also perform 5 strength training sessions, and the watch has never experienced a single reboot during those workouts. The issue seems to be strictly isolated to running activities.
