George Scott and Mac Cassin are back for the fifth and final episode in our training series with Wahoo Fitness.

This time out, Mac, Wahoo’s principal sports scientist, talks BikeRadar’s editor-in-chief, George, through five common training myths.

1) 90rpm is the best cadence for everyone

2) A change in body weight of 2% relating to dehydration negatively impacts performance

3) A lighter bike (or rider) is the best way to ride faster

4) Lactic acid is the reason for all of your pain during and after a hard workout

5) Once you hit 30/40/50/60, you will only get slower
