Sri Chinmoy believed that running is beneficial to physical health but also can give an inner spiritual fulfilment. Running teaches us determination, focus and reminds us of our aspiration to go beyond our previous limitations. Running is both physically challenging but, at the same time, gives an inner joy and satisfaction. Many runners attest to the fact that running can take us out of an ordinary consciousness and give a glimpse into a state of mind beyond our usual thoughts and emotions.
“Running is a symbolic sport in the sense that it reminds us of spiritual seekers continuously running towards the goal; it resembles the seekers running inwardly to achieve the ultimate goal in meditation.”
Sri Chinmoy 
Some of the spiritual aspects of running
“Self-transcendence gives us joy in boundless measure. When we transcend ourselves, we do not compete with others. We do not compete with the rest of the world, but at every moment we compete with ourselves. We compete only with our previous achievements. And each time we surpass our previous achievements, we get joy.”
Sri Chinmoy 
Self-transcendence is concerned with an attempt to beat our previous achievement and stretch our capacity. This self-transcendence can be measured in a race against the clock, but even if we can't beat our times, we can still strive to make a greater commitment and effort in our training and races. If we are detached from the outer result, we will feel joy from these attempts at self-transcendence. Whilst we may not have the capacity to beat others, we always have the opportunity to pursue our own self-transcendence attempts.
Running brings forward both our outer and inner determination. Running requires effort, focus and the willingness to challenge our body against the distance and elements. To complete a race requires a fixed mindset and determination to keep going.
Getting to know yourself
“When a runner focuses all his attention on a particular race, he is in a position to free his mind, liberate his mind, from uncomely distractions. Here one-pointed concentration is the pathfinder for a deeper meditative consciousness.”
– Sri Chinmoy 
Running takes us out of our comfort zone. It teaches us that we are more capable than we perhaps realise. To a non-runner, completing a marathon may seem an impossible task, but if we train, we realise we are capable of much more than we realise. Whilst running, we get in touch with a different part of ourself, and we learn more about our inner reserves.
Dynamism and inner peace
Question: Can running help get rid of frustration and anger?
Sri Chinmoy: Running is an excellent way to rid oneself of frustration and anger. If you are really angry with someone, go and run. After a mile or so you will see that your anger has gone away, either because you are totally exhausted or because the satisfaction that you gain from physical exertion has replaced your anger. 
A great benefit of running is that it shakes away our mental cobwebs. The dynamism of running helps us to get away from the petty concerns and worries of our mind. Dynamism is a powerful tool to bring to the fore more inner peace. When we are static, we become like a stagnant pool, when we move, it is like a clear flowing stream. The Sri Chinmoy Oneness-Home Peace Run combines both running long distances with an endeavour to share peace. Sri Chinmoy felt the dynamism of running across countries was an excellent way to share peace in a meaningful way. Running brings many of our good qualities to the fore.
How to bring spirituality into running
Self-transcendence vs competition
Rather than worrying about whether you can beat your competitors, focus instead on your own performance. Can you transcend your previous efforts? - Can you make the best possible effort given your circumstances? If you focus only on your self-transcendence, you will get joy from running - whatever the outer result. You will see fellow competitors - not as rivals, but fellow runners who can inspire your own efforts.
If we meditate before running, we will be conscious of our inner stillness and inner reserves which can help us in the outer running. Meditation teaches us to be one-pointed and bring all our awareness of one aspect. When we run, we can see our running as an extension of our meditation. Just bring all your focus on to the running - the rhythm of breathing. Don't get distracted by thoughts, but just try to be the observer of the running. When the body is running, at top speed, feel at the same time an inner focus and inner equanimity.
"Again, the runner's outer speed has a special kind of poise or stillness at its very heart. An airplane travels very fast, yet inside the plane we feel no movement at all. It is all tranquility, all peace; and this inner tranquility we can bring to our outer life. In fact, the outer life, the outer movement, can be successful only when it comes from the inner poise."
- Sri Chinmoy 
To make running a more meditative experience, we can concentrate on our breathing. We should feel our breath brings in not just oxygen but a divine energy. If we visualise we are breathing in cosmic energy and exhaling tiredness, we will gain more inner strength.
The inner value of running
"The main reason is that running reminds us of our inner goal. Whether we consciously run toward the goal or not, our very feeling that there is a goal helps us considerably."
- Sri Chinmoy 
If we value running as a spiritual exercise, then it can become something much more than just the outer running. When running, we can feel we are making inner progress and striving to reach our inner goal.
