If your legs are sore after two days of running, you can continue to run, but you need to reduce your running intensity and running distance. Leg soreness after two days of running is caused by anaerobic digestion in the leg muscles, lactic acid accumulation and muscle fiber fatigue, if the soreness is not serious you can continue to run, but you need to reduce the running intensity and running time. Before running, it is necessary to warm up sufficiently, fully stretch the muscle fibers and joint ligaments, etc., which can effectively alleviate the leg soreness after running. Do not rest immediately after running, you can continue to walk slowly for a period of time, so that the muscles can be fully relaxed, and effectively alleviate the soreness and pain after running and other uncomfortable symptoms. If the leg soreness is more serious after running for two days, and walking also has more obvious soreness and pain, it is not recommended to continue running.
