Burnham Square headlines 2026 Arlington Million at Colonial

Burnham Square brings a three-race winning streak and headline status into today's $1 million Arlington Million at Colonial Downs, anchoring a deep turf field that will likely be reduced to seven starters after Mercante's expected scratch. The Grade 1, 1¼-mile test on the Secretariat Turf Course goes as race 11 at Colonial Downs in New Kent, Virginia, with post time scheduled for 5:52 p.m. Eastern.

Colonial Downs is hosting the Arlington Million for the fourth consecutive year since the race moved from the shuttered Arlington Park, and the event again serves as the centerpiece of the track's Festival of Racing, which offers more than $2.6 million in purses across a multi-stakes card. The Million retains its traditional configuration as a 10-furlong turf contest for older horses, run over Colonial's expansive outer course that emphasizes stamina, rhythm, and the ability to sustain a run around sweeping turns rather than quick bursts of acceleration. With the race positioned late on the program, it sits squarely in the heart of national simulcast menus and advance-deposit wagering platforms, ensuring significant handle from bettors following the summer turf scene.

Morning-line favoritism belongs to Burnham Square at 5/2, a 4-year-old gelding who has quietly become one of the most versatile horses in training. Daily Racing Form notes that he enters off three consecutive marathon turf stakes victories, each earning triple-digit Beyer Speed Figures, and will attempt to add a Grade 1 turf win to an already secure Grade 1 résumé on dirt. Trainer Ian Wilkes shortens Burnham Square back to 1¼ miles after those longer-distance successes, and Brian Hernandez Jr. retains the mount for a horse who has shown the ability to sit just off the pace and grind relentlessly, an ideal profile for Colonial's long stretch where races are often decided in the final 100 yards. Handicappers have responded accordingly, with several national previews identifying him as the most likely winner if he maintains his current form and handles the cutback in trip.

Trying to topple the favorite is a potent one-two punch from Hall of Fame trainer Shug McGaughey in Fort Washington and Integration. Fort Washington captured the 2025 Arlington Million at Colonial, with Integration finishing third, and the pair returns for another crack at the same prize after productive campaigns at the graded-stakes level. Fort Washington, pegged at 5/1 on the morning line, has proven ability at 10 furlongs and tends to launch a sustained outside rally, a style that perfectly matched last year's race shape when he ran past Integration late. Integration, the 4/1 second choice from the McGaughey barn, already owns a Grade 2 win and Grade 1 placings and is widely regarded as a horse on the verge of a signature top-level score, with John Velazquez expected to have him well-positioned behind the leaders before asking for his run at the quarter pole.

Test Score adds another established Grade 1 presence to the mix as a 9/2 shot, having already proven himself against elite turf competition. Xpressbet's race-of-the-week analysis highlights Test Score's victories in major turf events such as the Belmont Derby and Pegasus World Cup Turf, underscoring his compatibility with firm ground and longer distances that mirror Colonial's configuration. Trainer Graham Motion has often excelled with horses that settle mid-pack and quicken through traffic, and Test Score fits that mold, suggesting he could capitalize if the pace is more demanding than forecast. Dresden Row, at 7/2, brings a different profile as a synthetic specialist with multiple Grade 3 wins who has transitioned to turf; Daily Racing Form notes his recent third in the Wise Dan at 1 1/16 miles on grass, a race that hinted he has the turn of foot to handle top company at slightly longer distances. Longshot Layabout (20/1) lines up from post 2 for Patrick Biancone, while international runner Gran Oriente, a Group 1 winner in Chile, offers a new variable at 10/1 for Saffie Joseph Jr. in his first major North American turf test.

From a pace perspective, most previews suggest a relatively measured tempo rather than a scorcher, which could favor versatile stalkers over deep closers. Dresden Row has shown enough early speed on synthetic and turf to attend the pace without becoming a sacrificial rabbit, and Gran Oriente is another candidate to be forward if his Chilean form translates into aggressive positioning. Burnham Square typically settles just behind that first line of horses, conserving energy before grinding into contention, while Fort Washington, Integration, and Test Score are more likely to stack up in the second flight or deeper, relying on sustained late runs rather than sharp bursts. If the expected scratch of Mercante materializes, removing one of the more tactical graded winners from the lineup, the early fractions could become even more controlled, amplifying the advantage for horses who can quicken and maintain momentum rather than those dependent on a collapsing pace.

The betting market has coalesced around a clear hierarchy: Burnham Square at 5/2, Dresden Row at 7/2, Integration at 4/1, Test Score at 9/2, Fort Washington at 5/1, Gran Oriente at 10/1, and Layabout as the 20/1 outsider, with Mercante effectively off the board pending his anticipated defection. National handicapping outlets emphasize Burnham Square's unique bid to become a dual-surface Grade 1 winner, framing the race as a referendum on whether his grinding style can repel the proven late kicks of Fort Washington, Integration, and Test Score over Colonial's demanding turf layout. For bettors, that sets up a classic Million puzzle: weighing the favorite's current form and versatility against the course-proven class of the McGaughey pair and the resume of Test Score, all while factoring in how a potentially moderate pace might tilt the race toward those closest to the engine rather than the deepest closers. However it breaks, the 2026 Arlington Million shapes up as one of the most intriguing turf showcases of the summer, with Colonial Downs again providing a stage worthy of the race's storied name.
