Running....

Hi
Well today, I was talking to a colleague. He has been running for the last 25 years. A lot of experience.I told him about my ambition to run a marathon. He said that running a marathon is an unbelievable experience. But needs a lot of training.So Im gonna pay attention to every bit of advice.
He invited me to go for a run next Thursday.(Thursday and Friday are his slow days). I told him about my issues with running. He said lenghtening my strides should reduce my impact issues.So I'm gonna go for a run next Thursday. Also I am going to buy a new pair of runners.I aim to do at least 5k plus.
One step at a time....
