What is YOUR Everest?

When I was a kid my Everest was the Ironman. Yup. I would watch it on NBC at home with my father and I would always be amazed watching the people finishing, some crawling, others rolling like a dog on a sunny day, anything to get to that finish line. Most of them would be crying and falling into their loved ones arms, relief washing over their faces. I sat in awe of these athletes. I was a competitive swimmer at the time so I had an appreciation for the 2.4 mile distance of the swimming portion. Add onto that 112 mile bike ride and a full marathon and I thought these people were super-human. And I wanted to join their ranks, someday. What's YOUR Everest?
