Warm up 5 mile progression, 4 minute walk to keep loose break, 5x300 meters hard w/ a 500 meter jog, about 2.5 mile cool down for 10.2 miles total.
Not sure what I was thinking but I hit that first 300 like I was running for my life, I haven't run that fast in years and maybe ever. It probably took some of the quality from the rest of the 300s but if that didn't wake up my fast twitch muscle fibers nothing will lol
