1x29 + 1x12. Basically just pedaled what felt correct up some climbs in a not all-out fashion. Data gels with the 3x20's I did on Monday and what GoldenCheetah pegs my threshy at as well. Good data, gains keep coming.
Thing I'm trying to figure out is my legs *always* die before my lungs do. It seems like if I can figure that part of the equation out I'll find some relatively easy watts. Maybe as simple as adding in another easy day between harder workouts. Or it could be because my last structured vo2 workout was in March. But threshy is so much more fun...
