I am now signed up for the MI Titanium Half Ironman (Aquabike). My brother is doing the full event (Half IM), but my Aquabike entry will allow me to swim and then bike. I'm not a runner, and I generally don't enjoy running distances greater than 1mi.
Sandbagging the bike at Naperville last year really sucked -- I like riding and I like riding at my best pace. This way I can go all-out and enjoy it.
Course distance is 2,000m swim and 56mi bike. Brother will then head out for a half marathon run while I eat cookies in the finisher's tent.
The bike course looks fairly flat, and is an out and back east-west. I'll be coming back to the pit heading west, so hopefully the prevailing wind won't be in my face the entire way home.
Not doing this for speed, more or less just want to finish it. Notionally I'd like to finish in under 4 hrs (45 min swim and then 18mph avg bike).
Event is out in August, but the prices go up after Dec 31st.
