66? Who am I kidding?

Ok ok. I'm a mathematician, so I sat down and mapped out my training program, and associated run types of long, tempo, easy, etc with a general predicted mileage. Then I consulted the charts of times likely at 10 miles given where I know I may be at fitness-wise. 66 minutes is a dream, once that is so unlikely to reach it's almost foolish to consider. So, if I accomplish that, then I'm a superstud. However, I do think that a more realistic if still unlikely goal to shoot for is 70 minutes, and if I were to finish the 10 miler in 72 minutes that's still a good thing. So, we'll see.
