I run the 800 and 1600 (high school), and below is the workout my coach gave me for today. I'm currently preparing for outdoor track (we don't run indoor), and I typically have 3 workouts a week, two that are more speed oriented and one that is more distance oriented. Recently, I haven't been able to finish my coach's workouts, and I'm wondering, is it my fault? I feel like I am putting a high level of effort into these, but I never seem to be able to complete everything my coach has planned. I don't know if his workouts are too hard, or if I'm just not trying hard enough. Need some opinions. Thanks.
Today's workout:
2 sets of (4x400 @ mile pace, 4x200 @ 800m pace)
90s rest in between every rep, and full recovery between the two sets.
I was only able to complete the first set of this workout before being completely exhausted. Maybe I'm going too fast and the paces I was running weren't my actual race pace? Or is the workout itself too hard?
