The past decade at Del Mar confirms an old maxim—pace makes the race—but the balance between speed, moisture, winds, rail settings, and maintenance has shifted repeatedly. Below are track trends on how each configuration has played since 2015 with a few subsets, followed by a fast-acting handicapping checklist.


Dirt Course Trends


Sprint Races (6–7 furlongs)


Wire-to-wire success averaged 54% from 2015-21, spiked to 60% in 2022 when the surface was sealed tighter, then dipped to 47% in 2023-24 after deeper mid-meet harrowing created a looser top layer.


Morning marine fog firms the rail; drying afternoon winds loosen the crown, allowing rally-wide closers, especially on busy weekend cards.


Post positions 1-8 win at similar rates; gates 9 and outward under-perform because the stretch is a short 919 ft.


Middle-Distance Routes (1 mile – 1 1/8 miles)


At the flat mile, tactical speed is essential: 61% of 2022-24 winners were no farther than 1 ½ lengths off the lead at the first call.


In 10-furlong events (e.g., Pacific Classic), closers captured 28% of races from 2015-24, reflecting a more even pace and longer far-turn run.


Post draws 3 through 6 have won 45% of the races.


Classic Routes (1 ¼ miles – 11 furlongs)


Five of the last six 1 ¼-mile winners were within three lengths of the lead at the mile marker—deep closers rarely sustain momentum around Del Mar’s sharper turns.


Front-running horses remain potent: Midnight Mammoth’s 2024 romp (48.2 / 1:12.9 splits) echoed Tizamagician’s 2021 wire-to-wire (49.3 / 1:14.8) victory in the Cougar ll stakes.


Deep closers succeed only when the second half is genuinely contested, as in Order and Law’s 2023 upset after mid-race pace pressure collapsed the leaders.


Turf Course Trends


Turf Sprints (5 – 5½ furlongs)


Raw speed still matters but is no longer absolute: from 2022-24, 45% of winners led gate-to-wire, 37% pressed/stalked, and 18% closed.


When rails are out 18-30 ft, the run-in lengthens, tilting advantage to mid-pack rallies; at zero-rail settings, inside speed regains the edge.


Turf Routes (1 mile and longer)


Rails set 0-12 ft favor ground-saving pressers/stalkers who cruise behind moderate fractions. Rails 18-30 ft tighten the turns and shorten the stretch; in 1 1/16-mile races, closers spike to a 41% win rate.


Post bias is mild overall, but at 1 mile and 8.5 furlongs, gates 9-12 win under 5% of the time due to two-turn positioning battles. You can easily eliminate posts 9-12 that are associated with horses.


Quick-Reference Handicapping Checklist


Morning fog or heavy marine layer: Upgrade inside speed on dirt and rail-skimming turf pressers/stalkers; downgrade wide closers early in the card.


Dry Santa Ana winds: Favor outside-draw stalkers that float into the crown; downgrade pace horses stuck on the rail. This mostly occurs in the Fall meet.


Turf rails out (18-30 ft): Promote wide-draw closers, fade inside speed at a mile.


Dirt sprints: Lean on horses showing quick early-pace figures; downgrade mid-pack grinders.


Repeat Del Mar starters: Thirty-two percent win again within the same season—respect "horses for courses."


Trainer–jockey combos: Juan Hernandez with Bob Baffert excels in juvenile dirt sprints; Antonio Fresu and Phil D'Amato dominate turf routes.


Scratch-reduced fields (< 7 starters): Expect chalkier outcomes; narrow vertical wagers and trim backups in horizontal bets. Odds-on favorites win 71%, one of the country's highest percentages.


Del Mar remains a pace-centric circuit sitting just ¼ Mile from the beach, yet success now hinges on reading subtler cues: when the cushion was last tilled, how the sea breeze modulates moisture, and where the temporary turf rail sits. Handicappers who monitor these levers, post draws, and key local horsemen maintain a decisive edge on the tote board. It’s important to remember that handicapping races involves much more than tracking trends. You must consider many relevant factors, as you can find in my Horse Racing Handicapping Article. Is the horse eligible for a forward or backward move? That’s basically what it comes down to—knowing how the horses will react (positively or negatively after their last race.
