The 10-Year Rule:

I was reading an interesting article the other day that basically said your running will peak roughly about 10 years after you begin in earnest, regardless of what age you start, as a rule-of -thumb.

In other words, even a 50-year old beginning runner would peak at 60.

I'm not sure how or where I fit into this, I've been running a long time but haven't really gotten serious about competitive running until a few years ago, anyhow I think this is a newsworthy concept.
