Final answer:
A marathon runner typically takes 24-48 hours to fully recover muscle glycogen if those stores were fully depleted during a race. The recovery time depends on several factors such as the intensity and duration of the race, the runner's diet and hydration, and their individual metabolism. It is important for marathon runners to consume carbohydrates and protein in the post-race recovery period to replenish glycogen stores and aid in muscle repair.
