Beating a dead horse: Advantages of weight loss vs ftp gains (in TRI)

[mcalista]

@Bigvern777

As for translating to performance - most tris the bike is quite flat. So when the course is flat your ftp and aerodynamics matter more than weight. So you may get more performance benefit from boosting your ftp it just depends. For the run from what I’ve read 10 lbs of weight loss can roughly correlate to 20 sec per mile.

This. Weight loss will probably make a bigger difference to the running leg than the cycling leg. And as you increase speed with a higher FTP, some of the FTP gains will be lost to increased aero drag. But a higher FTP will allow you to hold the same speed for a lower intensity factor, allowing you to keep more in reserve for the run leg.
