Recovery is not "passive rest"; it is an active process that makes you stronger. While sleep is your "Tier-1" strategy, fueling is "Tier-2." Eating a mix of protein and carbs within 60 minutes after exercise helps fix muscles and refill energy.
If you feel pain, you need to know the difference between "good" soreness and an injury. A dull ache might be normal, but sharp, stabbing, or radiating pain (pain that travels) is a sign to see a professional. For minor aches, use RICE: Rest, Ice, Compression, and Elevation. Also, check your gear — running shoes should generally be replaced every 250 to 500 miles to maintain support for your feet.
