2013 Running Goals - Is it OK not to have them??

It's been a while since my last post. I'm happy to report I'm still running! I have a 1/2 marathon coming up in a few weeks. I finished out 2012 with a beautiful trail run with my hubby along Lake Liganore in Maryland. It was idyllic and relaxing!

I'm already signed up for a few races in 2013. I don't really have any goals specifically for 2013 and I'm wondering if that's OK? Will I slack if I don't have something to work towards? Will it make running less rewarding?

What do you think?
