The Tight Turns of Monmouth

Monmouth Park

Time this evening that I should have spent poring over the lifetime past performances of every Breeders’ Cup pre-entry has instead gone to investigating the tight turns of Monmouth meme floating around right now, popping up in all sorts of articles and early analysis of the first World Championships to be held at New Jersey’s jewel box of a racetrack. Turns out, Monmouth’s sharp curves may well be as apocryphal as those of Pimlico. Below are comparisons of Monmouth to three other one-mile oval tracks.

Monmouth and Santa Anita

Monmouth and Santa Anita both have stretches of 990 feet and share a configuration of similar length turns and straights.

Monmouth and Pimlico

Monmouth’s turns are slightly longer than those of Pimlico, which has straights approximately 25 feet longer than those of Monmouth.

Monmouth and Churchill

Churchill has straights approximately 59 feet longer than Monmouth, making its turns shorter than those at Monmouth. Note the sharpness of the turn into Churchill’s stretch.

It’s possible Monmouth’s turns are steeply banked. Higher banks flatter speed and punish outside-running horses, which could explain the track’s reputed speed bias and Monmouth oddsmaker Brad Thomas’ contention in an interview with Dave Litfin that horses who run well on their left leads do better at the track (DRF, PDF, $). Overall, though, Monmouth’s turns seem like a minor handicapping factor. A bigger one will be the condition of the track’s surfaces in late fall, especially that of the grass. Thomas tells Litfin that he wouldn’t be surprised “if the turf is a little bit longer for the Breeders’ Cup races than it is in regular day-to-day racing during the summer,” which could be helpful to the Europeans.

Jessica,
Great work and a big help in handicapping. Love the fact that I was able to learn of you doing this through Equidaily too! Well done!

Wonderful work, Jessica! You need to resurrect this come Preakness time.

Glad someone has put this out there. I work with the folks at ESPN and every year we get to Pimlico and debunk the myth of “tighter” turns. It is basic geometry. An oval one mile around can only have slight differences in the curvature of the turns. We measured (using Google Earth)the curvature and found that Churchill is actually “tighter” by 1/1000th of a degree. The only thing that differs on various racetracks is the placement of the finish line and the point where they measure the length of the stretch. We only have a few seconds in an eight hour broadcast to make the point. You’ve got it on the web for all to see now. Good job.

How a horse handles the turns is certainly important but a more prominent factor at Monmouth this year will be the composition of the soil.

Its reputation for favoring speed horses is no urban legend. This will be evidenced in the BC Sprint where 14 runners are set to go (Mach Ride, a major contender, was recently scratched).

Attla’s Storm, trained by the red-hot Richard Schosberg, and Bordonaro (who is 10 for 19 lifetime) will be ones to focus on in this race. These two speedburners raced each other into defeat in last year’s BC Sprint at Churchill. They are both exceptional runners. If one draws much more favorably than the other, it could be the deciding factor. Attila’s Storm has a win over the Monmouth surface to his credit, Bordonaro does not. To round out this longshot trifecta, I would also consider Park Avenue Ball, the classic horse for the course.

Good luck.

interesting comparisons but the CD stretch is 1234.5 ft long and much longer than the stretch at MTH and more than the 59ft you indicated

Thanks for the comments.

Peter, you’re right that the Churchill stretch is 1234.5 feet versus 990 at Monmouth. The difference is made up by the slightly longer straights on both sides and Churchill’s finish line placement.

Pimlico’s turns may have the same angle as those found at Churchill, but the turns at Pimlico are not banked as much, which is what gives jockeys the feeling of tighter turns.

Another thing about banked turns–they help closers more than speed types. Front runners do far better at Pimlico than at Churchill. Closers are moving faster than the frontrunners (or otherwise they wouldn’t be closing but just plodding along in the rear) and are better able to maintain their momentum if the turn is banked. Think of short track speed skating in the Olympics. Obviously zero bank since it’s ice and if you have watched this sport for even a few minutes you can see it’s physically impossible to pass while turning.

Northfield Park has some of the most highly banked turns in harness racing and closers rallying wide are able to build up a lot more speed coming out of the final turn than closers at another half-mile track like Maywood Park where the turns are not banked as much.
