Intervals (Hill) 40:00 
4x 6min hill intervals on Mt Kaukau behind Lizzie's place. Dragged Magnus out to do them with me, which was good as I had someone to chase. Lost about 30m each interval despite trying to get to the same spot every time. Had trouble on one of them with hyperventilating and almost having to stop but sorted that out. Hasn't really happened to me before running until the last few weeks, so I'm not sure what thats about. First real hill interval session for a long time, so it felt quite hard!
