Notes
ROTB w/ hills. Set the treadmill for 7 minute miles. 1 mile w/u, then 1/4 mile hill and 1/4 mile recovery, all at 7 minute pace. Started at 3% and increased the hill by .5% each repeat for 5 hills, ending with a 5% hill. Got HR into marathon zone, then to lacate threshold of 175 during the last repeat.
