Zwift's Gorby, AKA "The Quitter," is a challenging workout indeed. With five rounds of five minutes at 110% of your FTP, some may not be able to finish. But if you're one to push beyond that torture, then the Pain Cave's Extreme version is right up your alley. Where the Gorby Extreme differs from the original is in the final two minutes of each interval. Here we have 6 x 5 minute blocks, each consisting of 3 min @ 110%, 1 min @ 115%, and 1 min @ 130%. If you find the original workout a challenge, this isn't going to be a walk in the park. More like a descent into Hell.
