Why it’s important
Knowing your FTP is important as it lets you set accurate and personalised training zones and allows other key metrics such as Training Stress Score (TSS) to be calculated.
If you’re following structured workouts on Zwift or RGT, such as the workouts that form the meat of the Hotchillee Winter Warmer Training Plan, whether you’re joining WOT (Watts on Tuesday) or doing them solo, the level of the efforts in these sessions is determined by the FTP that you have entered onto that training platform.
By dividing your FTP by your weight, you’ll get your w/kg at FTP value and this is used to determine your category on Zwift for Group Rides and Races, including the Gain Train
The w/kg category bands are:
A = 4.0 w/kg >
B = 3.2 - 3.9 w/kg (Gain Train First Class)
C = 2.5 - 3.1 w/kg (Gain Train Second Class)
D = < 2.4 w/kg (Gain Train Buffet Class)
How to test
An FTP is a tough session, so take a day off beforehand. Don’t stress too much if you don’t feel that you got the pacing spot on - the protocols are pretty robust and your numbers won’t be too far out.
To test for your FTP, you just need to follow a simple protocol on Zwift and then enter it into your account profile.
For RGT users, this video explains how to test for your FTP
You can also find more information about testing on RGT here.
Once you’ve completed a test, both platforms will automatically update your FTP if you better your previous test score in a subsequent test or on the Gain Train!
