Rest day yesterday. Did a two-hour ride this morning with 2x30' SST. The first interval was at 92% and the second at 95%. I had a 5' RBI in there and I could've done without it. I felt pretty comfortable during both. Average HR for the first was 123 bpm with an EF of 1.89; the second was 128 bpm/1.86. My heart's too old and lazy to beat much faster these days.
It was a cool day, so that kept my HR down.
Recovery run tomorrow, probably on the treadmill due to severe thunderstorms, then four hours of hill repeats on Friday. Taper starts Saturday.
