ALTOONA, Iowa – Friday night’s $75,000 Prairie Meadows Juvenile Mile kicks off a busy final weekend of the Thoroughbred meet. Featuring eight colts and geldings looking to stretch their nascent talent around two turns, the Juvenile Mile is headed by Cash Bonus and Sightforsoreeyes.Cash Bonus, a Lone Star Park shipper trained by Bret Calhoun, won a maiden race there June 19 before a troubled trip cost him when fifth, beaten 3 3/4 lengths, on July 11 in the $111,020 TTA Sales Futurity. The Corinthian colt, who fetched $75,000 at Lone Star Park’s Fasig-Tipton 2-year-old sale in April, is bred to relish the added distance Friday after that pair of five-furlong sprints.Sightforsoreeyes, who finished strongly in his debut here to win by 3 1/2 lengths on July 16, is trained and co-owned by Doug Anderson. After the Sightseeing colt’s maiden tally, Anderson said, “The longer, the better for him.”The Prairie Meadows Juvenile Mile is scheduled for 9:37 p.m. Central and precedes Saturday’s Iowa Classic Night, a series of seven Iowa-bred stakes races worth more than $500,000 in combined purses.
