THE racing community is mourning the sudden death of popular trainer Guy Walter, 59.
Mr Walter died of a heart attack on Thursday after overseeing a morning trackwork session.
He returned to his nearby home to have breakfast but took ill and collapsed. Despite the efforts of paramedics he was unable to be revived.
His funeral will be held at 2pm on Friday at Warwick Farm Racecourse.
Mr Walter grew up in Mudgee and participated in local pony clubs and shows.
In the early '70s Mr Walter had two stints working for legendary trainer Bart Cummings and one stint with Neville Begg. Mr Walter was strapper for Think Big when the horse won the 1974 Melbourne Cup.
Mr Walter started his training career on Seven Mile Beach on the south coast where he trained with the assistance for renowned horseman Kevin Robinson.
After five years there, Mr Walter moved his stables to Warwick Farm. After an initial struggle, metropolitan winners started to flow — most notably with Prince Invader who won 13 races including the Tamworth Cup.
Overall, he trained 26 Group One winners and his horses accumulated more than $40 million in race prizemoney.
In the early '90s Tie the Knot emerged as Australia's most talented galloper. He was trained throughout his career by Mr Walter, who referred to his days with the champion galloper as "life changing".
