With the temps well below zero, these were inside. Held 118-121 on the 4 90 second high cadence efforts. Really no problem with those. Could push it closer to 140-150 if needed. Then did 3x1 minute steady states at 330 each as a warmup for the 3x5k efforts. Held 350, 356 and 362 with just 2 minutes between efforts. Will take tomorrow with some endurance the rest of the week and the indoor tt on Sunday.
