I think that is a bad strategy…time should be the consequence of a properly paced bike leg, not a goal.
Time is based on a number of factors…power, aerodynamics, course profile, wind, etc.
And those numbers seem very high for the related times…I did Muncie 70.3 (which is a VERY flat course) in 2:19 at ~75% FTP and Racine 70.3 in 2:26 at ~79%.
