The 2015 Ladbrokes Challenge Cup Final promised to write another thrilling chapter in the rich history of Rugby League's most famous competition. For Leeds it was a familiar experience. The Rhinos were defending the trophy they won against Castleford in 2014, and were competing in their fifth final in six seasons. For legendary captain Kevin Sinfield and formidable forward Jamie Peacock, it would be their last appearance in the showpiece occasion. Hull KR were playing in the final for the first time since 1986. Their dramatic semi-final success over Warrington earned a generation of their loyal supporters the chance to see their team at Wembley for the first time and the possibility of watching them lift a trophy that had eluded the Robins for 25 years.
