#04 Race Development Forecast: The High-Paced Battle of Attrition

Pace Setters & Front Runners: With powerful front-runners such as Crimson Prince (2), Wannahavefun (12), and Nagisanoruna (16) all set to contest the lead, the battle for supremacy from the gate will be fierce.

Pace Prediction: We anticipate a scorching early pace, with the first 3 furlongs likely run in the high 34 to low 35-second range.

Key Factors in Race Dynamics

  • In a crowded field over Oi’s 1200m, an outer gate isn’t necessarily a disadvantage. It can allow a horse to avoid the inside scrum and position themselves smoothly in a favorable spot.
  • If Wannahavefun (12) and Nagisanoruna (16) manage to secure forward positions cleanly from their outside gates, they could dictate the race tempo.
  • Presto Emperor (14), benefiting from an outside draw that reduces the risk of being boxed in, also stands to gain from this strategic advantage.

Opportunities for Closers & Stalkers

  • Should the race unfold into a high-paced, grueling contest, horses that conserved energy in the middle or rear of the field will find a golden opportunity to unleash their finishing power.
  • Handen Drake (15), with his experience closing from behind in a graded mile race, is perfectly poised to capitalize on his stamina in such a scenario.
  • Doki Doki (13), renowned for his devastating turn of foot in the final 3 furlongs, possesses the raw ability to sweep past rivals in the straight.
