Yasso 800's can be a great predictor for marathon time. That is, if you're Bart Yasso. Apparently
it doesn't work for everyone. Regardless of whether I run a 2:51 - 2:57 marathon at Bizz Johnson, 10 800's at VO2max pace is an excellent workout.
Over the past few months I tended towards slower track workouts with cruise intervals, primarily because I felt I could only get 2 quality workouts in any given week. And since my target race is a marathon, a long run and tempo work seemed ideal. However, a buddy of mine suggested VO2max during the week, then a
tempo long run on the weekend. That means 15 - 22 miles, where 4 - 8 miles is at tempo pace (~6:45/mile) and the rest of the run is at easy pace (~8:15/mile). I'll give that a shot this week and see if my body protests too much.
