To do your best, you’ll want to concentrate on the moment. But, you can also find small ways to take mental breaks as well. While you are running, pay attention to the environment around you. Try to focus on the spectators on the sidelines of your marathon. Or, perhaps keep your focus on the trees or greenery. This will take your mind off your discomfort. If you are not in pain due to an acute injury, then you can generally compartmentalize the negative sensations connected with pain, thus minimizing its power over you. Don’t give pain more power than it should have. If you experience discomfort, start to think about all of the ways that pain can be good.  For example, muscles are often sore or in pain before they regenerate even stronger. Just be aware of your body and know how to differentiate “true” pain, such as shin splits, from “false” pain, such as muscle soreness. If you know that you are suffering from an injury, such as shin splits, then it is a good idea to modify your training regimen. You may need to run for shorter periods of time or distances. Try to develop a plan to build back up to your desired goals, but realize that you will need to be realistic about what your body can, and can’t, do when injured. There are some moments when pain and discomfort must be taken seriously. If you feel a sharp pain in your shin or hips, it is best to slow or stop running. If you start to experience tightness in your chest or severe stomach pains, stop and seek out help as well. When in doubt, trust your instincts and err on the side of caution. If you suspect that you are injured or if you are experiencing noticeable pain when running, it may be a good idea to talk with your physician. Explain your running routine and ask them for advice regarding potential modifications. View your visit as an opportunity to learn more about your body in order to maximize its potential.

Article: As of September 2018, Personal Blocklist works in the most recent version of Chrome (version 69.0.3497.100), but it may not work in previous editions. To update:  Open {"smallUrl":"https:\/\/www.wikihow.com\/images\/c\/cd\/Android7chrome.png","bigUrl":"\/images\/thumb\/c\/cd\/Android7chrome.png\/30px-Android7chrome.png","smallWidth":460,"smallHeight":460,"bigWidth":"30","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of an Android icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a><br>\n<\/p><\/div>"} Google Chrome. Click ⋮ in the upper-right side of the Chrome window. Select Help near the bottom of the drop-down menu. Click About Google Chrome  Wait for Chrome to update if necessary, then click RELAUNCH when prompted. Unlike Block Site, Personal Blocklist doesn't prevent users from accessing blocked websites; however, it does hide the blocked websites from Google search results. For example, if you were to block facebook.com in Personal Blocklist, you'd still be able to open Facebook, but no "facebook.com" websites would appear in Google search results. This is the page from which you'll install Personal Blocklist. It's a blue button in the upper-right side of the Personal Blocklist window. This option appears at the top of the page. Personal Blocklist will install. Unfortunately, blocking individual search results by clicking a link next to them isn't currently possible, but you can block a website from search results by going directly to the website in question. You can also type a phrase into Google to bring up a list of search results and then select the result that you want to hide. It's an image of a white hand on a red background that's in the upper-right corner of the page. A drop-down menu will appear. This link is near the top of the drop-down menu and contains the website's URL after it. Clicking this link prompts the current site's address to be added to Personal Blocklist. It's in the top-left corner of the Chrome window. This confirms your addition to the Personal Blocklist app. Your selected site will no longer return search results in Chrome. Try searching for your website's name in Google search (e.g., if you blocked Facebook, you would type facebook into Google). In the resulting list of links, you should briefly see the link to the website show up, after which it will disappear. Entering the blocked website's URL will still result in the website loading. If you want to block the website from being accessible in Google Chrome, use Block Site to block the website as well. One way that people can use to get around your restrictions is by using incognito mode, but you can enable Personal Blocklist in incognito to fix this problem:  Click ⋮  Select More tools  Click Extensions  Click DETAILS below the "Personal Blocklist (by Google)" heading. Scroll down and click the grey "Allow in incognito" switch {"smallUrl":"https:\/\/www.wikihow.com\/images\/d\/d5\/Android7switchoff.png","bigUrl":"\/images\/thumb\/d\/d5\/Android7switchoff.png\/35px-Android7switchoff.png","smallWidth":460,"smallHeight":394,"bigWidth":"35","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of an Android icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a><br>\n<\/p><\/div>"}.
