Bike FTP

I did my 8-Minute Test on TrainerRoad yesterday morning to see how much I have improved at cycling since the last time I did the test back in February.  My FTP (Functional Threshold Power) increased from 176 to 184.
How does FTP affect how fast you can ride your bike?  I’m glad you asked!  Here are some of my previous numbers to show how FTP translates into time on the bike.  Assuming I do my race on a completely flat course with no wind (ain’t gonna happen) and I don’t have to run after, this is approximately how long it would take me to do 90 kilometres:
(Dec 2011) 139 FTP – 2h46m
(Jan 2012) 147 FTP – 2h43m
(Feb 2012) 176 FTP – 2h31m
(May 2012) 184 FTP – 2h29m
So basically, if I could have even finished the bike portion of the race back in December, I would have been 15 minutes slower based on FTP alone.  I know that I couldn’t have handled 2.5 hours of riding my bike back then, let alone run after that, so the FTP is quite misleading.
Now, unfortunately for me, Ironman 70.3 Mont-Tremblant is anything but flat.  As you can see, there are grades ranging from a mild 2% to a leg burning 17.3%.  It should be interesting!  I’m glad I’ve been making good use of Sufferfest’s Angels bike ride for hill training.  I hope it does the trick.
