Better late than never they say. It certainly applies to this season's Performance Cycle classes – now we're in full swing after some initial confusion that came from a sudden change on GFDH's.
We kicked off this past Sunday with an assessment to find the wattage numbers we will be using going forward. I like to use very simple terminology that minimises any mathematical computations.
The week before I described how we experimented with pinning down two numbers;
… Instead I base my Life Time Performance Cycle classes on two numbers; PTP (Personal Threshold Power) and JRAP (Just Riding Along Power — AKA > Base Watts > VT1 / First Ventilatory Threshold Power). From these two rider identified threshold wattages, we can construct three meaningful power Zones;
- Recover zone — watts below JRAP
- Perform zone — watts between JRAP and PTP
- Improve zone — watts above PTP
Today we added one more wattage number – their 20 minute FTP watts. As you can guess, riders should have a lower 20 min average than a 3-4 minute PTP / Best Effort and be above JRAP / Base Watts.
Wait John, you just said you only use the two thresholds in class.
What's the point of adding a third number?
Adding the third point of reference helps you draw a straighter line. At least that's what my high school drafting teacher taught me. It's much easier to draw between two distant points, if you add one in the middle = it helps you understand if you're on the right path between the two known points!
