Check Your Fitness and Fatigue Without Going All Out

A submaximal fatigue test is a steady effort repeated regularly at the same power or pace. Because the effort is the same each time, changes in heart rate during the test and in how quickly your heart rate falls afterwards say something about your fitness and how fatigued you are. Several top cycling teams use these tests.

For cycling, ride steadily at your target power for 3 minutes, then ride very easy for a minute so your heart rate recovery can be measured. For running do the same thing with pace.

• Tests are detected and analysed automatically
• Configure the test separately for each sport on the settings page
• Use a fixed test power or pace so every test is comparable across the season
• Re-analyse existing activities to find tests you have already done
• Activities with a detected test are tagged #SFT so you can find them easily
• See power, efficiency, final heart rate and heart rate recovery for each test
• Record how hard the test felt (RPE) and how much longer you could have kept going
• Chart your results over time next to sleep, stress and other wellness data
• Plot test results on your fitness charts
