Eliud Kipchoge : (3) " I’ve always found the secret is to stay fit and treat sport as a profession. I chose sport as a passion. " - Eliud Kipchoge " Long runs improve your endurance but shorter intervals improve your speed. They are mutually beneficial for a distance runner. If you do 5k runs it will help your marathon. " - Eliud Kipchoge " If you believe in something and put it in your mind and heart, it can be realised. " - Eliud Kipchoge
