Lost track of the day of the week, sorry for the delay in posting. Today's session is a long threshold fartlek around the 4 hills. As per usual on this session, increase to a threshold effort on all the hills, long and short, and run steady between the hills (steady is just slightly harder than full conversational pace). Decide within your packs when to start and finish each effort and make sure you regroup between efforts without actually stopping.
