I am totally impressed. My longest tri is a 70.3.  I actually wonder if you are doing the same ironman as my husband in 2 weeks (Wisconsin?).  It's his first.

100 miles, double yikes.  Sticking through that means you can stick through anything.  Fantastic.  Thank you so much for sharing your experiences.  They sound really powerful.  I am totally with you in the humility front.  It's never knowing just what our body will do... and then, I am always shocked at the ages marked on the legs of some folks as they blow past me ;-)
