My gear sport did a software update approximately 2 weeks ago. I am a runner who often runs 5ks. I have a particular running trail that I use often. I used this trail so often that I know exactly how far a 5k is. Before the update, my watch tracked the mileage accurately. After the update, my watch does not track the mileage accurately. Every time I run a 5k (3.1 miles), it says that I only ran 2.6 miles. How do I fix this?
