We ask this to avoid any exercise that require lots of determination, time and energy.  Long distance running is one of those exercises, but can also be beneficial.
     First, running provides an opportunity for a person to gain inspiration and collect their thoughts.  For instance, Gary Dudney was a writer who had not  found  his footing in the writing industry, until he started running. He used this exercise as a stepping stone for creativity and brain storming ideas.  

    Next, running assists with scholarship foundations.  Allyson Harris, lost her teammate to spinal menengitis,  and  as a result a scholarship was named in her teammate's honour.  
      Futhermore, Laurel cooke benefit from running by raising money for charity from this sport.We both know this method used help others in the community while meeting different type of people.
