What is the typical lifespan of a racehorse?

The typical lifespan of a racehorse is generally around 15 to 20 years. While some horses may live into their mid to late 20s and even longer with excellent care, the average lifespan for a racehorse is influenced by various factors such as breed, genetics, care, and the stresses associated with racing. It's important to note that while some sources may suggest a range of 25 to 30 years, that is not the most commonly observed lifespan for racehorses, as many factors can shorten their life due to the rigors of training and competition. Thus, 15 to 20 years is a more typical and realistic estimate for the lifespan of a racehorse engaged in racing activities.
