The short version is that I finished much, much slower than I'd hoped due to heat, hills and cramping. But I felt great for the first 17 miles, finished in under 5 hours, am reasonably happy considering everything and I can't say I wouldn't do it again. But another marathon would have to be a lot flatter and during much cooler weather.
But the end result is that I am a marathoner.
Now I'm off to ice down, de-stink and get my party on. Further details later.
Thanks again for the support.
