Red Wind was made the ante-post favourite before the competition got underway, the fawn dog had won the Grand Prix and Midland Puppy Derby but in qualifying for the second round suffered a minor injury. Greenwood Tanist was the first shock of the competition as the 2-1 favourite failed to qualify after going lame.^[1]

Round two saw Red Wind recover from his injury and secure a nine length victory in a fast 28.70. Another favourite, Ballymac Ball showed a strong finish to catch long time leaders Loyal Accomplice and Magna Hasty in his heat.^[1]

In the first semi-final Quare Customer won from Magna Hasty and Drumgoon Boy. In the second semi-final Red Wind faded after being well placed and was eliminated, the race was won by Ballycurren Garrett with Ballymac Ball and Captain the Killer claiming the qualifying places. Red Wind was found to be lame again after pulling a muscle.^[1]

In the final Ballymac Ball broke well with Quare Customer challenging, however Ballymac Ball maintained a healthy lead and ran out over three lengths in front recording 28.72, a new final record.^[5] The favourite Ballycurren Garrett had missed the break and encountered crowding with the others, leaving one of the sport's biggest owners George Flintham still awaiting success in the Derby.^[1]
