Run 37:42 [3] 4.4 mi (8:34 / mi)
shoes: LaSportiva Akasha size 10
Same on road course as all of last two runs, but slightly faster. Felt left cartilage early so eased back some more, but that discomfort then moved to the left hamstring. Not bad, just a "warning" type level of discomfort.
By about 4 hours later, the left cartilage became significantly more painful and stayed that way for 24 hours.
