Notes
11 mins WU; 3 x 10 mins threshold + 3 mins recov.
Did all of the threshold in Harrow Lodge Park on grass - quite challenging. But quite enjoyed it in a strange sort of way.
I was late going out so it was starting to get dark by the end which was a bit disconcerting - the evenings are starting to get darker now.
Back of my heels are a bit sore & uncomfortable.
