I used strava for the first time yesterday and when I paused it at the end of my ride and recorded it my time was 1hr 45min 22sec for 27.6 miles. When I looked it up on my computer this morning it had my time as 2hr 8min don't remember the seconds for total moving time. I know the first time was accurate because I looked at my watch when I started and when I finished. Has anyone had similar experiences?
