Is it wrong to hate a race?

When I was in college, I did something that later bothered me: I signed up for a marathon and began training for it. I actually got up to the point where I was doing 10 mile runs on the weekend. However, I realized that, while I could push myself to do it, I didn’t enjoy it. Running for hours at a time wasn’t any fun for me. I figured if I hated it at 10 miles I’d really hate it at 26 miles, so I never actually ran the marathon. Also, I’m curious if people read the details of questions.
