• i dont know...

    THat seems to suggest the pros at IM distnace are riding at 80% of FTP, and i've read lots saying that an IM marathon is between 15-20% over your standalone pace, but not found anything yet on 70.3's.

    Have had a look around TP and it looks to 75-80% is the more advised number for age groupers...

    feels quite low, espeically as even if i run a HM PB i'm unlikely to be close to the front of the pack...
