TrainerRoad’s ramp test estimates Max Aerobic Power [MAP] (best one minute power from the ramp) and takes 75% of that estimate as the rider’s FTP. I’m one of those riders that consistently has an FTP that’s more like 70% of my ramp-based MAP so my FTP is generally set a little high & I’m constantly futzing around with it.
Recently I did an AC/HA test, TR ramp test, & some regular hour long efforts. As has often been the case, my hour efforts were 6% to 8% less than MAP-based FTP results.
I created a hybrid ramp test based on Hunter Allen’s recommended 20 minute FTP test protocol. At the end of this post (if I remember!) you’ll be able to review the Hunter Allen protocol. Instead of a 20 minute constant power as the test I spliced in the TR ramp protocol.
The results of the Hybrid TrainerRoad ramp test were within a few watts of my full hour efforts. So maybe that’s a better measure than just a regular ramp test. Something to think about if you’re a rider that experiences this same sort of issue.
Anyhow, it seems certain this isn’t the first time somebody has thought to do this. But I couldn’t find anything else about it on the forum…so I thought I’d post.
