Folks,
Recently picked up a Garmin Vivosport to replace an old watch that died. I'm a runner, and move indoors to the treadmill when the weather gets cold. So far I've done about 4 runs outdoors of about 5 miles each. Today I did an indoor treadmill run of about 5 miles (according to the treadmill, which is new/accurate), but the Garmin picked it up as a 6.3 mile run. I appreciate the bonus, but I'm more interested in accuracy. I've been where I can edit the total distance, which is fine. Is there any way to increase the accuracy?
