Black toenails are common in runners, usually resulting from repeated trauma to a toenail inside the shoe. While running, the toes strike the front or roof of the toe box, especially on downhill routes or long distances. This can cause bleeding beneath the nail, called a subungual hematoma. The dried blood produces a dark red or black appearance and may loosen the nail over time. Improper shoe length or width, excessive movement within the shoe, and swelling from heat or high-mileage add to pressure on the nail plate. Certain toes, particularly the big and second toes, absorb the greatest impact. Less common causes include chronic ingrown nails, fungal infection, toe deformities, or rarely tumors that also create discoloration. A podiatrist can evaluate the nail bed, relieve pressure, and guide a safe return to running while preventing nail deformity. If you notice unusual coloration in the toenails, it is suggested that you make an appointment with a podiatrist for an exam, diagnosis, and ongoing treatment.

How to Prevent Running Injuries
Many common running injuries are caused by overuse and overtraining. When the back of the kneecap starts wearing out and starts causing pain in your knee, this is commonly referred to as runner’s knee. Runner’s knee is a decrease in strength in your quadriceps and can occur if you’re not wearing properly fitted or supporting shoes. To prevent runner’s knee, focusing on hip strengthening is a good idea, as well as strengthening your quads to keep the kneecaps aligned.
What Are Some Causes of Running Injuries?
- One cause of a common running injury is called iliotibial band syndrome.
- Plantar fasciitis is also another common injury.
- Stress fractures can occur from overtraining, lack of calcium, or even your running style.
