In Aux courses des Longchamps, Juan Gris presents a vibrant scene filled with dynamic figures and lively colors. The painting captures the excitement of horse racing, with jockeys and horses depicted in a fragmented, cubist style. The use of bold colors such as reds, blues, and yellows adds to the energy of the scene.

The background features abstracted shapes that suggest a bustling racetrack atmosphere. The painting is characterized by its cubist technique, where forms are broken down into geometric shapes and reassembled in a new way. Gris employs oil on canvas, allowing for rich texture and depth in the colors. The composition is balanced, with a rhythmic arrangement of figures that leads the viewer's eye throughout the work.

This approach is typical of Gris's style, which blends realism with abstraction. Juan Gris was a prominent figure in the Cubist movement, known for his innovative approach to form and color.
