Missed by that much

Ran today with my new shoes and had another crack at working out the Nike GPS, unfortunately I didn't figure it out to till the end of my run.When I checked out the distances on line I found out that I had run 4.95km, missing the 5km mark by 50m. DOH, never mind another chance will come at tommorows Matilda Bay run.Pleased to report the new shoes where fantastic.
