I've never seen anyone out running who enjoys themselves. Someone actually said that to me. I said I felt the opposite, all the runners I know enjoy their running. (Well most of the time.)
That got me thinking. In 'Running With The Mind of Meditation' by Sakyong Miphram he discusses how much runners complain about pain when they are running. He think points out the best way to deal with this by accepting the pain, but not making more of if than you need to. It's very illuminating to hear a blend of eastern and western perspectives and this is just one chapter of the book that is packed with wisdom and understanding.
The book is full of gems that nourish the runner's mind, and there is even a free download from the website.
Danny Dreyer talks about how Chi Running should become a holistic practice that percolates in to every aspect of out life. There are various sides to Chi Running - the running form, the focus on posture, relaxation, high cadence, running at different speeds etc. For me personally the mind body link is one of the main things which sets Chi Running apart from other approaches to running. Running with the Mind of Meditation is an absolutely essential read if you enjoy the Chi Running philosophy and want to look deeper in to the mindfulness and meditation side of it.
I'm going to blog a lot more about this book as I feel it's an absolutely essential read for the Chi Runner if you have any interest at all in mindfulness. You might not all be ready to 'get in to' that side of it right now, but when you are, give this one a read.
