Can you produce high aerobic power and repeat it? Today we are testing your ability to repeat high intensity aerobic efforts with 2 x 8min intervals. An athlete with a well developed aerobic engine will be within 5% of their first interval. We will also play with the numbers a little to estimate your FTP. 8min Power can be used to check your FTP, but not normally used to set your FTP. Treat each 8 minute interval as if it were the only effort. Give it FULL-GAS!
