With any luck, this week's Breeders' Cup Challenge Series races will be just as thrilling as last week's. Both the Hollywood Gold Cup and the Smile Sprint Handicap featured roaring comebacks in deep stretch by their respective winners, First Dude and Giant Ryan. Three more &quot;Win and You're In&quot; races will be held this weekend, highlighted by another Blind Luck-Havre de Grace matchup in Delaware.\r\nDelaware Handicap\r\nThis Grade 2, 1 1/4-mile dirt race for fillies and mares 3 years old and up will be a five-horse field, including a showdown between the two favorites, Blind Luck and Havre de Grace. The two horses have faced each other five times, with each horse winning two of those matches. The one race neither won was last year&rsquo;s Breeders' Cup Ladies' Classic, in which Blind Luck finished second and Havre de Grace finished third. The win would be big for both trainers as well; Jerry Hollendorfer (Blind Luck) and Larry Jones (Havre de Grace) have each won the Delaware Handicap once already.\r\nBut, to gain a second victory in the race they may have to face the most accomplished trainer in the race&rsquo;s history, Todd Pletcher, who is tied with Henry Clark for the record most wins as a trainer: four. Pletcher may run Life at Ten, who deserves consideration as the defending champion, despite having a rough year after controversy at last year&rsquo;s Ladies' Classic when the horse showed no interest in running. Only four horses have won the Delaware Handicap in consecutive years, most recently Nastique in 1988 and 1989, with no filly having won the race more than twice.\r\nYour browser does not support iframes\r\nGreenwood Cup Stakes\r\nSmall park -- big race. The Greenwood Cup, an endurance-testing 1 1/2-mile route on dirt for 3-year-olds and up, is also part of the Breeders' Cup Challenge Series, meaning the winner of the race will earn an automatic entry into the BC Marathon. Last year&rsquo;s running, despite the extreme distance, was not settled until the final seconds when A.U. Miner barely edged out Alcomo by a neck in the final strides. A.U. Miner headlines another strong field this year. A.U. Miner will be ridden by top jockey Calvin Borel, who is coming to give the 6-year-old a leg up on his competition. The $200,000 purse of the race is supplemented by the $50,000 from the Breeders' Cup for the nomination.

Saturday, one filly or mare will honor her name by winning the 56th running of the A Gleam Invitational Handicap, a seven-furlong sprint that sends the winner into the Breeders&rsquo; Cup Filly &amp; Mare Sprint. Last year's winner Sweet August Moon came in fifth in the November Breeders' Cup event, losing to Dubai Majesty.\r\nThis week's races to watch\r\nFriday\r\nFriday Night Lights racing fans will want to check out this card at Penn National.
