Nearly 10 miles on a route I have only run a few times in my life. It is on too busy of a road for my tastes: I prefer passing about 5 cars in 90 minutes. I had about 50 cars pass me on this run, which is silly for most of you who live in a city, but I prefer the solitude of my country runs. The GPS whacked out on me today, as it has done in the past, so I never knew my true mileage. After it uploaded to Strava I see what happened - for some reason it locked into a location a mile plus down the road from me, so at 0.5 miles it had me at 2.0 miles - so odd.
