You should NEVER have more in the tank
Ask yourself: "Can I give more?" The answer is usually: "Yes". - Paul Tergat
Paul Tergat was a Kenyan professional distance runner in the late 90s and early 2000s. He was the first Kenyan to set the marathon world record in 2003 with a time of 2:04:55. He won 5 straight XC World Championship titles from 1995-1999, setting the record for most consecutively won XC Championships. He also won two half marathons in his career. Paul Tergat believed that you usually have more in you even when you feel tired or finished. Next time you have a hard training fay or workout, see if you have more in the tank. Use the final bits of energy to have the best workout you could possibly have!.
