Tempo

So I'm in week 1 of a 14 week 1/2 marathon training program concocted by Smart Coach. I start out at 16 miles for the week and top out somewhere around 30 by race day. Not huge mileage but I'm doing a lot of speedwork so I'm curious what the outcome will be. I didn't start keeping a training log online until March of last year so I can't really remember how many miles I was running in preparation for the same race a year ago but MAN I feel great. I'm so excited at the possibilities. Today was my first tempo run of the plan so I did a warm up mile and a cool down mile and 3 miles in between at a 9:13 pace. (It was actually supposed to be a 9:31 pace but I didn't realize I had transposed the numbers in my head by mistake until I got home and looked at the schedule. oops) The pace was difficult to hang on to there at the end but I didn't feel like I was running all out either. I know I couldn't have done this a year ago. I felt like I owned that treadmill!
