What Is a Long Distance Run?


Updated January 25, 2014

Definition: A long run is the highest mileage run of any week in your training schedule. The mileage of your long run depends on what race distance you're training for. For a runner training for a 10K, a long run might be 8 miles. Marathoners may run 20 miles for a long run. Long runs (also called long distance run) are usually done at conversational pace, usually at about 70-75% of max HR.

Most runners do their long runs on Saturdays or Sundays when they have more time. The benefits of long runs include: helps improve your endurance by strengthening the heart and opening the capillaries; strengthens your leg muscles and ligaments; teaches your body to burn fat as fuel; and develops your mental toughness and coping skills.

Also Known As: long slow distance run (LSD); long distance run
I'm training for a marathon and this weekend I'm up to 15 miles for my long run.
