To drop some science, contrary to popular belief, soreness is not caused by lactic acid accumulation (which causes immediate muscle discomfort) but by actual microscopic muscle damage. Specifically, cellular damage post-marathon is best measured by the presence and production of Creatinine — a marker that indicates damage to skeletal and muscle tissue (which by itself may indicate chronic kidney issues, since healthy kidneys filter Creatinine) — and increased Myoglobin levels in the blood stream. One study concluded that increased levels of Creatinine persisted more than seven days post-marathon while another study discovered the presence of Myoglobin in the bloodstream for 3-4 days post race. Both of these studies clearly indicate that the body needs rest after a marathon to fully recover from the cellular damage caused during the race.
