Den Haag halve marathon

My new running friend and I travelled up to The Hague today to race. My friend has done it before and highly recommended it due the great organisation and the flat fast course. The only problem was that it was in the afternoon and unusually hot. However, I knew I was in good shape and was confident that I was in shape to run a pb as I've been training so hard.
Admittedly I've recently picked up a hip/glute problem , but I gritted my teeth and smashed my four month pb by a couple of minutes. It hurt and I never particularly felt good but a pb is a pb!
