    1. it became a popular approach for endurance athletes looking to gain that competitive edge. These days triathletes, cyclists, swimmers, mountain bikers, marathoners, and other runners commonly spend time training or living in elevated locations.

      Research on this text: Almost all endurance athletes train at high altitudes. The Olympic 1500 meter runner Josh Kerr went to UNM and he occasionally trains in New Mexico, because of its high altitude and low humidity.

    2. Imagine arriving at the 1968 Olympic Games in Mexico City, ready to take part in the competition of your lifetime. You’d spent your whole career building towards this moment, only to discover that being over 7,400ft above sea level (where Mexico’s capital resides) left you struggling to catch your breath. Suddenly, performing at your peak was disappointingly out of the question.  Suffice it to say many athletes weren’t happy with their results

      Research on this text: A lot of the athletes at the 1968 Olympic games in Mexico city did complain about the high elevation affecting there performance. Here is article supporting this statement: Elevation, Records, and Controversy

    3. Nestled in the Ethiopian mountains, Bekoji is a small, unassuming town with less than twenty-thousand residents, yet one impressive reputation. The Guardian once called it “the fastest place on Earth,” owing to its success at producing gold medalist endurance runners, an athletic category dominated globally by Ethiopian and Kenyan runners. One crucial factor is Bekoji altitude: a breathtaking 10,500 feet above sea level.

      Because of the high elevation of Bekoji, it has produced a lot of Olympic gold medalist.

    4. Of course, while high altitude = low oxygen environments, you don’t have to go quite so high to reap the benefits of this form of training. At the foothills of the Rocky Mountains in northern Colorado, Boulder is regarded as a mecca for American elite distance runners and comes in at the comparatively modest 5,430 ft.

      You don't need to go very high in order to gain the benefits of low oxygen environments.

    5. One of the best things about heading to a high altitude with a watch like Polar Grit X Pro is that you can use its amazing outdoor features. Not only can it withstand temperatures as low as -20°C (-4°F), but this sports watch also includes superior navigation technology with Komoot, route and elevation profiles to track where you’re at and tell you where you’re headed, and an altimeter, compass, and coordinates. Plus, you can discover how you performed on up and downhill sections with Hill Splitter™. It’s the ideal wearable tech for adventuring in the mountains.

      Purpose of this text: One of the purposes of this text is to advertise the Polar X Pro.

    6. Shortness of breath and headaches are common, so take the first couple of days to adjust and ease into your new surroundings, especially if you are transitioning to an exceptionally high altitude.

      You will get shortness of breath and headaches the first couple of days.

    7. Likewise, pushing yourself to do as much training as possible during a short burst of high-altitude training will stress your body out, weakening your immune system and limiting your ability to produce more red blood cells. So, give your body time to adapt when you first arrive by sticking to easy runs and low or moderate-intensity workouts. After the first few days, if you feel good, then you can increase your pace.

      Stick to easy runs and dont push yourself too much.

    8. Finally, you’ll discover you’ll need longer to recover, especially during the first few days, as your body will receive less oxygen. So, it’s okay to take extra time for rest when you arrive and additional days between training sessions to allow muscle recovery.

      It will take you longer to recover, because your tissue will be receiving less oxygen. You should focus on resting more to allow for a full recovery.

    9. developed by the Univesity of Texas, USA, this approach for elite athletes involves permanently living and doing light training above 8,000ft but completing hard training below 4,000ft, where their muscles can work harder with more oxygen.

      Accuracy of this text: This text shows a point of accuracy because it mentions where this training approach was scientifically confirmed to be true in Texas.

    10. In order to make new red blood cells, you’ll need lots of hemoglobin, the protein contained inside them that is responsible for delivering oxygen to your tissues. To boost your stores, you should eat lots of iron-rich foods, like beans, red meat, and dark, leafy greens. Add these to your diet before you travel and continue while you’re at altitude and when you get home.

      The proteins in hemoglobin are responsible for delivering oxygen to your tissues. You should focus on eating a balanced diet in order to maintain these proteins.

Also, If there was a per-review by some type of running coach or fitness expert, that would in increase the credibility of this article.

    12. Red blood cells have a life cycle of around 20 days

      Accuracy of text: According to the National Institute of Health and other sources, red blood cells have an average life span on 120 days not "20 days". nih.gov

    13. there’s every chance you could find yourself up in the mountains on your next holiday. It could be a ski break or an opportunity for long hikes. Whatever the reason, spending time in an elevated location is a great way to experience what it’s like to do some high-altitude training.

      Try and find every opportunity to get yourself up into higher altitudes.

    14. So, what exactly is high-altitude training? Simply put, it’s the practice of spending time in places high above sea level so your body adapts to less oxygen, enhancing your athletic performance. For some, this approach helps them compete competently at a high altitude. For others, it boosts their ability to perform at a lower altitude.

      High altitude training helps your body adapt to performing with less oxygen.

      Research on this text: The high elevation at the this Olympics mainly affected the distance runners and swimmers, but it is believed that it actually helped athletes in the long jump, high jump, and pole vault.

    17. we will examine why athletes train at high altitudes, the reasons for this training style, the benefits, and how you can try this approach even if you aren’t a professional athlete.

      Purpose of this text: To examine why athletes train at high altitudes and how you can apply this approach into your own running habits.

    18. Well, how long do you have? Most coaches recommend spending at least two weeks at altitude, although it takes at least four to begin experiencing any real performance enhancement.

      You should spend a least four weeks training at altitude.

    19. However, the adaptation to altitude begins very soon after you arrive, so your body should start producing more blood cells by the end of the first week. That means even spending seven days at altitude could be enough to train your lungs in addition to your arms and legs.

      Your body starts adapting to the altitude quickly, by producing more blood cells.

    20. Low altitude includes anywhere less than 4,000 feet above sea level, so you need to set your sights relatively high. At around 7,000 feet, such as Flagstaff in Arizona (the highest point on USA’s Route 66), you’ll begin to feel the effects of your elevated location without too many of the adverse side effects.

      You should train at altitudes around 7000 feet above sea level in areas such as Flagstaff Arizona.
