Faster Thursday-12km

I originally had planned on running at lunchtime but given the forecast is 27C and I was hoping to get a quality workout in, rather than a slog in the midday heat, I decided to run this morning at 7am.
Did the usual "College Run" which takes me from work up to Lane Cove shops and down Longueville Rd, then through the back streets of Riverview before entering St Ignatius College.
Back out onto River Road before returning to work. A good course for tempo/fartlek style running with a couple of nice hills. I ended up running 12km in 56:02 so 4:39/km.
