Why do a blog for aged runners?

When I started running in the 80s most runners you saw out and about and at races were youngish.  I know that is a subjective but most of them were in their 20s and 30s and mostly male.  I came back to running after a 15 year break and saw some major changes. If you look at a race profile these days there are more women and a lot more older folk.  Now in my mid 50s I put myself in the older category.  However if you read the magazines, blogs and look at the equipment providers there is a huge focus on younger runners. So I decided to share my experiences of coming back to running as an older runner and also share the experience gained with older runners in my club who are phenomenal runners in their 60s and 70s.  They are what I aspire to.
