One of the smartest things I did was get a coach to help me put together my training plan. I am one of those runners who like to train on his own and can usually motivate myself to get out on the road, even in the rain, so I felt that a coach would be a great way to put together a run training plan that I could use at any stage of my running career.
I was right. I have kept bits and pieces of a training plan I got more than 4 years ago and have been able to incorporate it into the various training plans I have used over the years. Get a coach. Even if you only use him/her for a little guidance for your training plan. You won't regret it!
