Schedule and motivation


A half marathon is 13.1 miles — half the distance of a marathon. Half marathons are a popular race distance for those looking to take on an endurance event, but who may not want to spend the time it takes to train for a full marathon.

Use our half marathon training plan to prepare for your race, and if you need some motivation, take some pointers from our list of tips.


Half marathon training schedule: 12 WEEKS

St. Jude Memphis Marathon Weekend participant


Our plan has your long run on Saturdays, but you can do your long run any day of the week that works best for you, as long as you're consistent. Long runs build the physical and mental stamina to cover the miles on race day.

Your midweek runs should be done at a pace that feels easy to you (a pace at which you can carry on a conversation). Easy runs burn calories and build mileage but should not put cardio stress on the body.

Rest days means rest. Recovery time is vital to increasing your strength and stamina.

Cross-training can be any low-impact, non-running activity (weight training, swimming, cycling, walking, etc.). If you need an extra rest day, use your cross-training day to recover.


Run the mileage at your pace for each day leading up to the race.

Know your plan. Training for a half marathon takes time. It’s easy for life to throw distractions your way, so make sure your training runs are built into your schedule. Use a daily planner or your smartphone to block off the time you need and keep your training plan a priority in your busy life. Schedule your run in your day like it’s a meeting you just can’t miss.




Be consistent. When something comes up that can’t wait, know that missing a training run or two won’t derail you. But stay committed to your race-day goal. When the runs get long or the weather gets hot or cold, don’t stop. It’s the difficult runs during training that will strengthen you the most for your race.




Run with a friend. Some people thrive on running alone, but for others, solitude can be discouraging during a tough run. You may not have a friend who can run with you the whole way, but asking someone to start off with you or join in for the last few miles can help break up a challenging run.




Befriend your local running store. Your local running store is a great place to ask about group runs and to find like-minded (and like-paced) running buddies. It’s also the best place to get fitted for proper footwear. Running shoes should be bought based on the support your foot needs, not on the color or style of the shoe, and running in worn-out shoes can increase your risk of injury. The running community loves runners of all shapes, sizes and speeds, so take advantage of their knowledge!




Mix it up. Use your long runs as a chance to explore! Map out nearby parks, trails, forests or areas of town you want to discover, and watch the miles fly by.
