Personally I hate the idea of a 20 minute all out test...even thinking about it kills me. My approach - set the FTP manually and do a workout, specifically Sufferfest's 'A very dark place'. Put on your big boy undies and go to that dark place with them and if you don't feel childbirth pains, push the FTP up until you do! Then tell your wife that childbirth has nothing on Sufferfest...this is the best part. Let me know how it goes!
