Notes
Cut-Down Interval
1500m at 10k pace / 1000m at 5k pace / 800m at 3k pace / 500m at Mile pace / 300m at 800m pace
This is a "race week" set. I shortened overall distance (usually do this starting at 2000m at LT pace and end w/2 x 500m). The 1500m felt the worst (felt "gassed") - ran this about 30 min after my strides (did stretching and core work in between). Need to start interval 10-15 min after strides. Felt good after. Did not hit my MaxHR until the 500m (and exceeded it by 10 on the 300m).
I've felt this "twinge" in the my upper left thigh in the groin area the past several days. In the 300m run (where I accelerated to 5:18 pace for the final 110m, I felt it "go"). I stretched after this run but have to be really careful (I do groin, leg, thigh, etc. stretches every day so this could be an area of concern).
