mental techniques to improve your running.Some runs may be a period of hard work, and the more you try to run through it, the worse you feel.37 This allows you to feel better the next day. When you let your brain rest, it sets your body up to feel safe.The brain says, “I can listen to my body, and I can take care of my body." This trust relaxes you, making runsmore enjoyable.Positive self-talk improves performance of runners in hot conditions. It indeed contributes to betterresults. Interventions (十 预) including self-talk training are more effective, which redirect your mind fromdiscomfort, tiredness or other ideas that might get in your way. For example, you think to yourself “I can dothis" — you're actively not thinking or engaging in negative thoughts. 38If you need to make a run more fun, challenge yourself to a speed play. For example, run slow for 30seconds, then medium for 10 seconds, then fast for 20 seconds. 39 Try running slowly to one tree, thengoing at a reasonable pace to a mailbox.40 When you train your mind, you can make runs that feel great happen more often. When you gethome from a successful run, make a note — literally pen to paper or on your phone —- of the reasons why itfelt good. It will be a reminder of why you started running in the first place.A. You can also use objects as markers. B. Give yourself the option to try again.C. Training your mind is just as essential, though.D. Preparations before running are really necessary. E. You're advised to increase your training intensity.F. Performing a mental review is strongly recommended.G.
