Ironman Louisville : Official Thread (Page 45)

yeah I still have no clue why a 12/27 is better than a 12/25?

dumb it down for me a bit...I know that right now I have 2 cassettes up front, in the back I have 10. On my old road bike I had 3 up front and the extra one was called a 'granny gear' by the bike shop guys.  Is the extra cassette up front better for hill climbing?  I live in a very hilly area and have had no problems with my current set up.  Yeah some of the hills are tough and I have to stand on the bike to climb them but will the extra few teeth really make a huge difference?  I know IMKY has rolling hills but are they hilly enough that you need to swap out your cassettes?

Protein can help as another poster claims, but if you are also eating solid foods and are still hungry then you just arent getting enough calories period.  Im 6'0" 170lbs and I take in about 350-400 calories per hour on the bike and a little less on the run.  You probably need to switch to something a little stronger than gatorade or something that you can concentrate to get more calories in the same amount of liquid.

It's been in the mid 60s here for the past 4 days... this is not helping me train for the Louisville heat!!

Rant over...

Question for those who have done an IM before....I am scheduled to ride in a MS 150 ride on 9/12-9/13.  Is this doable in your opinion (as far as being recovered)?

It has been much cooler than usual here in Cincy too.  Actually, it has been chilly!

It just depends on how fast you recover.  Everyone recovers at a differnt rate.  Also, how fast are you planing on riding the MS 150?  Easy pace? 

Just an FYI for all of you looking at changing your cassettes.  Don't forget that by going from a 11-23 to a 12-26 etc that you lose some gears in the middle.  Not "lose" them, but you might lose your 18t gear for a 17t or something like that. Not sure which one's you lose, but they switch them up.  It doesn't seem like much, but you will need to get used to it.  I have a gear that i love to push when i'm in my big ring and when i got race wheels with an 11-23 i kept clicking back and fourth in the back trying to find that gear and i couldn't.  Eventually i adjusted and its fine now.  But its just something to think about.

You guys should come train in Georgia, the high for the next 10 days is between 87-92...and that's actally cooler than it has been over the past few weeks.
