pretty good 8.5

I went out for a run and had a pretty good one. Endomondo is still making me crazy. suddenly both the distances and probably the pace are wrong, or not what I am used to. It is marking the kilometers at different points, significantly different, so I am not sure if this is right and all along it has been wrong or if now it is wrong. ANd that affects the pace trackiong. I thought I had a good strong, not fast but strong and probably average or slightly better than average pace but it tracked me at a slow pace. Maybe I just need a real GPS running watch to know that it is being tracked properly.
