The jumpers will be out in force this weekend on the Maryland and Virginia steeplechase circuits.

Beginning at noon today, the Old Dominion point-to-point offers an eight-race card at Ben Venue, Va.

The featured Old Dominion Hunt Cup, a 3 1/4-mile timber race, is the seventh leg of the nine-part Seven Corners series for owner-riders, and has attracted a six-horse field including undefeated Cookin 'N Lookin, who has carried Paul Cramer into the series lead with 20 points. Among others entered is last week's surprise winner at Middleburg, J.M. Robinson on Wee Pet.

At 3 o'clock, in Monkton, Md., John Bosley IV will look for his second straight victory in the S. Lurman Stewart Memorial steeplechase aboard 8-year-old Old Question. Last year, Old Question won by three lengths, ahead of the 1982 Maryland Hunt Cup winner, Tong.

On Sunday in Davidsonville, Md., the 11th annual Marlborough Hunt meeting at Roedown features the $1,000 Roedown Cup, a three-mile open timber race. Jay Meister, 23, will be out to repeat last year's victory on Tigre's Houdini. Post time for the first of nine races is 1.
