Unless I really can run 18.8 mph....
Which would be awesome!
(BTW - my legs look exactly like that when I run)
I used it again last night on the group run and it had my max speed as 18.8 which is just ridiculous. The overall time was 35 minutes and it says I went 3.59 miles but I think it was closer to 3.2 miles. Even with the correct data I had a decent run. Though I learned an important and valuable lesson (which should have been obvious).
Never, ever, eat Burger King onion rings 5 minutes before a run. Especially when it's still over 90's degrees out.
I won't disgust you with the results of my error in judgement.
