Things were pretty intense for Ireland's fittest families last week, as they raced through a muddy obstacle course to hold onto their finalist positions. The second set of the final four families go head to head tonight, with again - the weakest group being eliminated. Olympic boxing champion Kenneth Egan, international rugby union coach Eddie O'Sullivan, Irish hockey star Nikki Symmons and Clare hurling manager Davy Fitzgerald are all there to help mentor them. The show is presented by Mairead Farrell who recently said that competition got so stiff between some of the families, that a row broke out. However, that won't be shown on the telly. TUT. Boo-erns.
