A horse's speed can change by fifteen percent based on how much water is in the soil
Soil moisture levels on turf tracks can shift horse racing odds by fifteen percent, as the delicate balance of water and grass elasticity dictates how much energy a 500-kilogram animal can safely exert.
A horse's speed and safety are deeply tied to the physics of the ground beneath its hooves. On turf tracks like those in Newmarket, soil moisture maintained between 15 and 25 percent creates the perfect level of firmness. This specific hydration allows grass fibers to provide 20 percent more grip than dirt surfaces, helping to prevent the slips responsible for 70 percent of equine injuries.
