Cushioning: Grass provides a natural cushioning effect, which can help reduce the impact on your joints and muscles. This can be especially beneficial for runners who are prone to knee pain or other injuries. Cement, on the other hand, is a hard surface that can put more stress on your joints and muscles, increasing the risk of injuries.
Traction: Grass provides better traction than cement. This is especially important when running in wet or slippery conditions, as it can help prevent slips and falls. Cement can become slick when wet, making it more challenging to maintain your footing.
Shock absorption: Grass helps to absorb shock and vibrations, which can reduce the impact of running on your body. This can help prevent injuries and reduce muscle soreness after running. Cement does not provide as much shock absorption, which can increase the risk of injuries and muscle fatigue.
Resilience: Grass is more resilient than cement, meaning it can withstand the impact of running without becoming damaged. Cement, on the other hand, can develop cracks and uneven surfaces, which can create tripping hazards and make it more difficult to run safely.
Temperature: Grass is cooler than cement, which can be especially beneficial when running in hot weather. Cement absorbs heat and can become very hot, making running uncomfortable and potentially dangerous. Grass, on the other hand, stays relatively cool, even in hot weather.
Overall, running on grass is generally easier on the body than running on cement. However, it's important to note that both surfaces have their own advantages and disadvantages, and the best surface for you may depend on your individual needs and preferences.
