come on now 3 times 60 is 180. 180 divided by 8 is 22 or so. so instead of an 8 mile tempo at 5:02 pace he is at 4:40 pace. seems like quite a difference.
Yeah, I get that he's running faster, I just don't understand why he's talking about running 9 minutes faster in the marathon. Maybe if he did 3x8 miles, all of which were 3 min. faster than the previous year. I dunno, maybe it's just taken out of context or something.
