It's a great sport. Started in my late early 40's, and still going strong more than 10 years later.

Looking at youtube videos can be helpful, as it at least gives you a basic idea of what to work up to, but you really just need to ride. When you start a lot of things are going to be too hard/overwhelming (that is if you're anything like I was), and you'll walk some parts of the trail. But if you keep on riding a couple of times a week you'll be amazed at how quickly you develop the skills needed to ride at an intermediate level. Also, putting on road/rail trail miles can really help get those legs toned up.

I'd suggest heading up to Alum Creek, where they have a nice mtb trail system. Phase 1 is the easier, with Phase 2 being for more advanced riders. Here is the state park brochure with the trails:

But these days there are better places to get your mtb maps if you use a smart phone. Here's the link to the mtbproject page for Alum Creek:

You can also use trailforks.com:

Or singletracks (requires membership, but you can get a free one by submitting useful data).

Check out your local club - COMBO. They may have group rides focusing on new riders.

Good luck.
