Crossfit?

Today I ran 10 miles (not for time) and completed it without too much trouble. When I was first invited on the run from the Gulf Coast Hight School cross country team (my old high school) I immediately thought no way, I've already put in my years of running.  I gave it a little more thought and responded with "of course I'll join." For the past 2 and a half years or more I have only been doing crossfit as my workouts ( as you can tell from my blog posts). As you may notice I hardly ever do any running, and when I do it's not much more than 100m here and there. An interesting thing happened on he run too. Mentally I felt so much strong than I ever have in long runs. 10 miles didn't seem hard at all to me and I have to thank crossfit for that as well. It may have hurt physically but mentally it wasn't very challenging at all. But isn't Crossfit just about lifting weights and getting bigger? Of  course it's not, and I think I proved it to myself and others today. Crossit creates balanced fitness over broad time and modal domains. Our goal is to not be elite at one thing, but be good at everything. I feel as though I have been given some great programming through Crossfit Redline as well as OPT, that has increased my fitness dramatically. Back in high school when I was running cross country that's all I could do. I couldn't manipulate a barbell for my life back then. Now that I have been involved in crossfit for a few years now I'm stronger than I've ever been, and can still run 5k races, as well as distance runs such as the 10 miler we did today. There is obviously no reason to destroy your legs logging 50+ miles a week when you can do Crossfit once a day which takes less than an hour. I haven't run anything over 3 miles in the past 3-4 years and completed 10 miles today without much trouble. I'd say Crossfit works. Why wouldn't you want to sign up?
