Improvers and beginners night

Young girl came along for the first time today (in front, all in black wearing a hat)
Said her ambition was to run a mile without stopping.
I ran with her and deliberately wouldn't tell her how far we had gone.
I said just tell me when you really feel you cant run anymore.
When that time came we were on 1.6 miles....and I cajoled her into running for 2 miles.
She was thrilled.
