"The challenge, was it worth it? Yes! Definitely worth it. There are times that I can sort of march, that I was never able to do before. I can go longer distances when I walk my dog and I don't feel like my knee is going to buckle." -- M.E. MD


"The challenge was worth every bit, I mean, it just gets you all excited about (it) and you want to go do it again. That's what life's about, it's challenges and pushing yourself to another goal." -- E.W. All American Over Sixty TriAthlete
