5K at 10K race pace

A 10k run tonight with the first 5k starting very slowly and building gradually. The 5K back was to be at around 10k race pace. I felt I was doing fine and close to target; and my pace felt as if I were on target, but I timed the last K and my watch disagreed.

A good run, if you take out the slower than wanted pace. I definitely have to mark my route!
