Training Zones

Time for a quick detour into training zones. I have a power meter on my bike, which is a device which measures how much work I am doing at any given moment. Using a power meter, your training zones are defined in terms of your Functional Threshold Power. FTP, as it’s known, is just the maximum average power you can sustain for approximately 1 hour, measured in watts (W). In my case, right now my FTP is approx. 285W.

Given that, the zones are defined as follows:

2Endurance56-75
