So after using zwift for a few weeks, I've today decided to have a go on Sufferfest. I set up my account, installed the software on my laptop, logged in and started looking through the training programs. I decided to have a look at the 4DP fitness test.... somewhat unfortunately titled "full frontal". Just as I was clicking through to it, my wife walked into the pain cave. First thing she saw was "full frontal", and the first thing she thought was that she'd caught me having a bit of quiet time
