The Sufferfest: Using a Power Meter


The ‘Sufferfest’ videos are by far the best training videos that one can use ( One challenge that I’ve found with the videos is relating the Rating of Perceived Exertion (RPE) scale of 1-10 used in the videos with the power recorded on my Powertap or Computrainer.  Fortunately, one Sufferlandian has created an excellent workbook which will convert your Functional Threshold Power (FTP) to the RPE scale. This is, of course, useful for anyone who needs to also use RPE.

The basis for the calculations are given here, along with other excellent advice and tools for using Sufferfest on a Computrainer.  There is an Excel file where you enter your FTP, recovery FTP and max FTP. From that, you get Sufferfest RPE values as shown below.


If you like to use Computrainer in ERG mode you will even get the necessary data to create ERG files.

A great tool which makes the Sufferfest videos even more effective.  Highly recommended for all Sufferlandians.

  1. I suggested that time be incorporated as a factor for mapping RPE to power. A simple suggestion is to use the mapping between RPE and power as per the table as is for the first 2/3 of the workout and then drop it by 5% for the last 1/3. A more complicated scheme could be devised but seems overkill. The idea is not to make the workout too easy but to follow the workout creator’s intent by using what we know about how power output will (should?) decrease for the RPE over time.

    • That’s a really good point which I hadn’t thought about. Thanks for suggesting it. Readers should also check out your software. Especially if anyone wants to do the Tour of Sufferlandria!
