According to Danny’s wife Norma:
“Danny died suddenly this morning of a heart attack.  It is the way he would have wanted to go but of course a big shock to us all.  I have all the family here so am very lucky.  We will let you know the funeral arrangements etc. later.   Perhaps you could let everyone know the news.
Best wishes,
Norma”
Danny was the President of the World Mountain Running Association and worked tirelessly to promote the sport.  This past September after over a decade of trying, Danny finally succeded in getting the IAAF to recognize the World Mountain Running Trophy as an official “World Championship”.
