The annual Rolling Rock steeplechase races, which have benefited handicapped children for almost 50 years, have been abruptly ended.
The races, held with a few exceptions since 1934 on the Mellon family estate of Rolling Rock, at Ligonier, 60 miles east of Pittsburgh, have been more a social than a sporting event.
Over the years the sponsors, the Mellon Trust and the Rolling Rock Hunt Racing Association, have contributed more than $1.2 million to the Rehabilitation Institute of Pittsburgh, formerly the Home for Crippled Children. The association, made up of a group of people from the Ligonier area, functions only to conduct the two days of racing at temporary facilities.
To ease the financial pain to the institute, the Richard King Mellon Foundation announced that it would grant it $500,000 over the next five years, giving it time to find new sources of funds.
33,500 at the Final Event
The cancellation came after the races last month drew 33,500 people, 4,500 more than last year. The association estimated that it raised $52,000 this year. Of $1.25 million in prize money distributed by the association in 1982, about $100,000 went to Rolling Rock.
The sponsors cited such factors as ‘‘the need for other use of the land, higher labor costs and the need for increased security in regard to public safety.’’ They said they had reluctantly made ‘‘a thoughtful decision based on a combination of economic and practical factors.’’ There have been reports that the site would be converted into a golf course or used for condominiums.
The Home for Crippled Children became the races’ chief beneficiary five years after they began. They were canceled during World War II and in 1966, when danger of an equine virus arose.
The sponsors’ statement surprised Richard P. Mellon, adopted son of the financier Richard King Mellon, and Alfred M. Hunt, of the family that founded the Aluminum Company of America. Lenny Bughman, the announcer who has called the races for 36 years, said he was unaware of the plans.
The races were run at the estate put together in 1921 by Richard Beatty Mellon. Many devotees of the steeplechase thought it was the nation’s most attractive setting for that aristocratic sport, as spectators viewed not only the thoroughbreds leaping the temporary barriers but also the fall foliage.
As a side note - one the most recognizable Rolling Rock beer logos is actually of a steeplechase fence - the one with the white rectangle and lattice at the bottom
