1. Try Some Self-Talk
2. Break Up Your RunDividing up your run into smaller segments will make the distance feel much more manageable. For example, if you're running 20 miles, think, "OK, it's four 5-mile runs." At the start of each new segment, visualize yourself just starting out on a new run with fresh legs and just focus on getting to the end of that segment.
3. Remember: It's Not Always Easy
As you're doing a long run, remind yourself that it's not easy to train for a long-distance event. If it were, everyone would do it, right? Remind yourself that you're taking on a challenge and the difficulties you face will make your accomplishment all the more worthwhile in the end.
4. Find a Mantra
Picking a short phrase, such as "One step at a time," that you play over and over in your head while running can help you stay focused and centered. It can be your inner motivation when you need it most. You may already have a favorite phrase to use as a mantra, but if you don't have one, check out these sample running mantras and marathon quotes for some inspiration.

5. Use ImageryWhen you hit a rough patch, try to imagine yourself as an Olympic athlete who's headed towards the finish line. Envision your running form as smooth, graceful, and relaxed. Think of a runner who you really admire and imagine yourself running just like him.
6. Play Counting GamesIf you run where there are a lot of other runners, try this game: Pick out a specific article of clothing, such as a white running hat, to look for during your run. Then count how many runners you see wearing it. If you do a lot of running on the roads, you can also do this with cars of a certain model or color.
7. Make Post-Run PlansI love deciding what I want to do after I finish my run, especially if I'm running in morning. I'll ponder something basic, such as what to make for dinner. It helps me organize my day and gives me something to look forward to after the run.

8. Visualize Your Race
If you're training for a race, such as a marathon, picture yourself running the course -- every mile -- and crossing the finish line. Picture how you want to pose for your photo as you run through the finish. Try to see the clock with your goal time (if you have one) displayed. Imagine what you'll be thinking as a volunteer puts your race medal around your neck. Think about how it will feel to see your loved ones at the finish line cheering for you.
