Hi,
I ran the Manchester Marathon on Sunday 27th April 2025, and was using my one month old Forerunner 255. I started a new activity and the device got a GPS fix as expected.
However when I crossed the start line and pressed "start activity" the device shut, down and restarted. This endless restart loop continued until KM 25 (approx 2 hours), and then stopped and appeared stable finally.
So for the first 2 hours I was unable to use my watch to keep track of my pace, which totally ruined the experience.
Is this a known issue?
Really not happy and considering a refund as I have lost confidence in this watch and would hate this to happen at my next marathon.
Please advise
