I have been riding since March of last year. Maybe I should have said I ride the ceturies at a pedestrian pace, to make it more clear. I have ridden three centuries, and the all have been around nine hours. These were the organized type rides, like the Amtrak Centuriy. As far as my bike goes, I have a Cannondale. CAAD 5 frame. My spin classes are twice a week. Basically I need a 7 hour century in order to complete an Ironman. The Ironman that I have entered is IMCDA, in Idaho, late June. The race starts at 7;00 am. I have 2 hours and 20 minutes to complete a 2.4 mile swim. Assumming I can do that, I move on to the bike. The swim is two 1.2 mile loops. The bike leg is similar, two 56 mile loops. The final leg must be completed by 5:30, there is a cutoff for each loop as well. Finally I have until midnight to do the marathon. In 5 marathons, my time is 6 hours. So if I add up my standalone times for each, I am bumping up again the 17 hour disqualification time.
