Distance runners often worry about “hitting the wall” during training or races—that terrible moment when negative thoughts become so overpowering that they make it difficult to continue.
Hitting the wall typically happens around 20 miles in a marathon, when the body's supplies become exhausted. At this point, many runners feel exhausted and discouraged, slow their pace, have trouble focusing and want to quit or walk.
“Generalized tiredness, unintentionally slowing their pace, the desire to walk, and shifting focus to just surviving the marathon appear to be particularly common characteristics of it,” said Dr. Alistair McCormick, an exercise psychologist in England who co-authored a new study. “A marathon becomes a real mental battle when runners ‘hit the wall.'”
Psychological blocks are an extremely common experience for recreational endurance (耐力) athletes, according to the study. To learn how they affect people, sports psychologists asked 30 recreational runners and cyclers about the psychological demands of training, preparing for and participating in competitions.
“Recreational runners and cyclists found it stressful trying to find the time to train, McCormick said. “What was also interesting was the number of potential banana skins they met with before and during competition-disasters that could cause the athletes to lose their focus and their motivation to keep persevering.”
These roadblocks included difficult environmental conditions and equipment failure, problems with nutrition or making a mistake, the study reported. The athletes in the study said they fell these obstacles (障碍) affected their motivation and concentration, negatively affecting their overall performance.
According to the study, 43 percent of marathoners are likely to hit the wall during a race. Finding ways to move past those kinds of experiences, then, could have major benefits for an athlete's performance and well-being.

Must-See Attractions
Most visitors begin their Amsterdam adventure in the Old Centre, which is full of traditional architecture, shopping centers, and coffee shops. You'll also want to check out Amsterdam's Museum Quarter in the South District, which is great for shopping at the Albert Cuyp Market and having a picnic in the Vondel park. The top museums to visit there are the Rijks musuem, the Ann Frank House, and the Van Gogh Museum.
If You Have Time
There are several other unique districts in Amsterdam, and you should try to explore as many of them as time allows. The Canal Ring is a UNESCO World Heritage Site that was originally built to attract wealthy home owners and is a center for celebrity spotting and nightlife today. The Plantage area has most of the city's museums, including the Jewish Historical Museum, the Scheepvaart Museum, and the botanical gardens.
Money Saving Tips
Unless you really want to see the tulips (郁金香) blooming, avoid booking between mid-March and mid-May. This is when hotel and flight prices rise.
Look for accommodations in Amsterdam's South District, where rates are generally cheaper than in the city center.
Buy train tickets at the machine instead of the counter to save a bit of money.
Instead of hiring a tour guide, hop on a canal boat. They're inexpensive and will give you a special point of view of the city.
