...but only briefly, at about 15 mins into the run. I think I was waiting for Sarah to tell me it was 15 mins but she didn't, so I lost my mental rhythm. Anyway I resumed running again and ran an extra 30 seconds at the end so all in all about 24 1/2 minutes.
On to W7 and if I can get the breathing right, I am confident of getting through non-stop!
