The Janney's Mill Bowl, at two miles over Glenwood Park's established hurdle course, may well over shadow the six other races on the Middleburg Hunt's point-to-point card Sunday.

Only four points separate the four leading horses in this spring-long battle for the First Colony Life Trophy signifying the owner-rider hurdles championship of Virginia. Only two races remain after Sunday, so every time these gentlemen-riders saddle their chasers, the tension mounts.

Kool Kake, Kevin Palmer's speedy mare, leads the parade going into Sunday's race. The 9-year-old Clem-Queen Victoria chestnut has won its last two starts at Warrenton and Piedmont after running second at Casanova and third at Rappahannock. The Casanova entry has 15 points.

In second place, only a point behind, is Alfred Knowles' Mr. Jam, the winner at Rappahannock and Blue Ridge. Another Marylander (Knowles is from Goshen). Charies (Chick) Owens' High Peak, is tied with Virginian Randy Waterman's Joanne's Brother for third place with 11 points each.

The open hurdle race will begin the program at 2 p.m. Cofeatured are the Middleburg Bowl, an open timber race at 3 miles, and the Middleburg Hunt Plate at three miles for owner-raiders.

THe latter is a crucial race in the Seven Corners competition with two leaders, Mike duPont and Randy Rouse, scheduled to go to the post only a half point apart. The two top contenders for the women's championship, Patty Cassel and Diane Deeds, are scheduled to take up their battle in the Journey's End Bowl, also over the three mile timber course.

Glenwood Park, one of the finest steeplechase tracks in the country, is one mile north of Middleburg.
