Weird situation today while trying to use my new instinct solar while running on a treadmill. I usually run for two hours every day and I record on my Apple watch between 6 to 8 miles depending on my speed. Today I noticed that while I was running/walking on the treadmill my Garmin watch was not showing any pace at all and therefore the mileage was not increasing. I ran for 2 hours and it only recorded .14 miles, impossible - the treadmill showed 6.5 miles, I read that I may need to caliber the watch but I have to run at least 1.5 miles. How can I calibrate if during two hours only recorded .14 miles? Any ideas? This is a brand-new watch.
