Do the difficult things while they are easy and do the great things while they are small. A journey of a thousand miles must begin with a single step.
Lao Tzu has certain themes that he returns to over and again from different perspectives and viewpoints. Self-mastery is one of them. The ability to conquer your own doubts and shortcomings is a vital part of achieving enlightenment, but it is equally important in your daily life.
You can use many of his teachings as guidance while planning a tough endeavour such as running a marathon. Training is best accomplished little and often, building up slowly and carefully, aware at all times of the lessons and warnings that your body is giving you. Running is a perfect opportunity to empty your mind of worry and care; to simply be in and of the moment. It can be a deeply meditative time.
I hope that everyone who has run the Reading Half-Marathon today has succeeded in their goals, and that the experience has helped them in all the ways they hoped, and some that they never expected. I would especially like to send warm good wishes to X&HTeam-mate Paul Staples, for whom this race is just another milestone on the road to the London Marathon in May. To him, and all the other brave and noble souls joining him, may the road rise up to meet you.
