Hey Denise,
Just wanted to give you a HUGE congrats on finishing IMAZ! I've been lurking here for many months, and wanted you to know how much I enjoyed following your IM adventure. You've inspired me to try an iron distance race this fall (not Ironman- but Redman in OK). You are sooooo amazing, and I loved being brought along on your journey (I couldn't wait to wake up and see how you did). Congrats again!

Anyway, my question is this: how did you pass the time on the bike for so long? I've run marathons before, and I can always find ways to pass the time, but on a bike I can't blank out (go brain-dead) like I can when I run. What are some tricks/tips that worked for you when riding for so long. My longest ride has only been 3 hours, and it was a stretch keeping my mind busy. I can't imagine doing that for an additional 4-5 hours. I use my headphones on my rides, but can't do that race day.
Any help would be greatly appreciated! Thanks!
