We're back for episode two in our training series with Wahoo Fitness. In this episode, Wahoo's principal sports scientist, Mac Cassin, talks BikeRadar's George Scott through fitness testing. 

What is a fitness test, why should you do one and what options are out there? While Functional Threshold Power may often be the go-to test, Mac also explains why FTP isn't always the answer.
