Great work Fred. Enjoyed your sharing of your motivational thinking during the race. Congrats!
Yes I was crazy to ride a new bike. Inline with doing an IM I guess 
Cheers,
Fred.
Fred, for the 1:30 in order of lowest to highest hanging fruit:
Transitions 10 minutes Swim 10 minutes Bike 20 min Run 20 min
You gotta come up with 30 other minutes from nowhere…seriously though, you can get down to 10:40 pretty easy from where you are today. Those final 30 minutes that you want to shave off will take lots of fine tuning and lots of base work trhough lots of frequency…leave the car in the driveway and glue your ass to the bike for the next few years. A few more years of base work will certainly be a big help.
