This comment made me grin yesterday when I bumped into another teacher I started the school with but hadn't seen in several weeks!
My garmin goal was 10,000 calories in a month, which I completed at the weekend, and afterwards worked out that to lose a pound in weight you must eat/burn off an extra 2,500 cals, so I should therefore be approximately 4 lbs lighter!
I also had compliments from somebody in the group above at run club last night who hadn't seen me run since the beginners group and said I had improved loads. Kept me going at full speed ahead for the remainder of the run! :)
