"Start slow, arrive early"
From the moment you wake up on race morning, everything you do has an effect on how well you can run the Ironman marathon.
Swim strategy:  Seeding is critical.  Conserve energy.
Always move!
Bike strategy:  Respect the marathon!  This is not a bike race!
Ironman begins at mile 90 on the bike.
"An Ironman marathon is 20 miles of hope and 6 miles of reality." - Cam Brown
The marathon begins at the 13 mile mark.
