To build endurance and aerobic efficiency we need to perform long steady efforts. Today's session comprises of a pair of sub-threshold efforts. After opening the interval with a Zone 5 surge, the remaining time will gradually increase over the duration of the effort. Observe how much this increase in power affects your heart rate.
