Age Grade Calculators for Cycling?

[mcneese.chad]

Not a calculator, but some data on FTP related to age, from TR and their riders:

The Bell curve of cylists - how fast are the average TR users?

Moar data!!! It seems like people want to see what’s “TR Average” and compare themselves to that. I’ve broken everything down a lot more. While I was doing this I wonder if we’re breaking new ground here…I don’t think anyone else has this much accurate data on riders. Insights: You get slower as you get older (duh). You can see that there’s a steep decline starting at 3.5-3.75 FTP/kg for men and women when you compare age in 10-year buckets. For both men and women, there’s a large drop off…

Another option is the one available through Intervals.icu, that takes your data and compares it to their compiled info with respect to age groups.
