I'm using the NYRR Virtual Trainer program for my fall half, which is on October 5th, and today is day one of the 10-week training program.
I love this product from NYRR. I input my recent training history, how many days a week I'm running, current long run distance, recent race result, fitness level (i.e. height and weight) and injury history, and then it spews out a training program tailored to me, complete with training paces for the different types of runs I'll be doing.
So today, I have 3 miles Regular Run. I guess that would equate to general aerobic miles in other plans.
