I did IMC last year. It was my first and I messed up the pacing on the bike and spent way too much time walking the run.
I am doing whistler and am going to do much better I hope.
I have run 6 or so open marathons. I know when I am going to hit th wall.
With the ironman marathon the pace is considerably slower than for an open but you are not starting with a full tank either…
When do you hit the wall in your IM marathons if at all?
