Hi everyone,
running 325 mile in 7 days sounds very tough I mentioned it to my uncle Malcolm Campbell who used to be the president of the world ultra marathon runners association.  He told me it takes a special kind of athlete to achieve these feats of endurance.  I suppose he should know in 1985 he ran a race across America called the Lou Gehrig Race for life. This meant covering over 3500 miles in 3 months that works out at 40 miles a day plus fund raising dinners and events the two athletes involved were Marvin Skaggerbord from the US and Malcolm Campbell from the UK  and they were able to raise over one million dollars for the charity that for a cure to the disease known as Lou Gehriggs disease.  So any one who goes for these amazing endurance feats have my utmost respect.  Best of luck to the runners
