China News Service, Beijing, May 23 (Reporter Xing Chong) Due to sudden changes in local weather during the race, a "Hundred-Kilometer Cross-country Race of the Yellow River Stone Forest Mountain Marathon" caused casualties.

As of 8 o'clock in the morning on the 23rd, a total of 151 participants were retrieved from the search and rescue, 8 of whom were treated for minor injuries in the hospital, and 21 participants had lost their vital signs when they were found.

　　What is mountain marathon trail running?

Yan Yi, deputy editor-in-chief of "Runners World" magazine and general manager of Panda Super Mountain Track By UTMB, explained his doubts in an interview with reporters: The mountain marathon is not simply "moving" the city marathon to the mountains, but to the event organizers. , Competitions with stricter requirements for contestants.

　　Yan Yi has many years of experience in trail running and mountain marathon competition and organization.

In his view, marathon, mountain marathon and trail running are different types of competitions and should not be confused.

From the point of view of the venue, marathons, as road running sports, are mostly held on the main roads between cities; mountain marathons are mostly held in the suburbs of cities, while cross-country races are mostly held in the wilderness far away from the city.

　　The bigger difference between the three types of events lies in the ups and downs of the road.

"We know that if a marathon race sets a record, it needs to be recognized by the World Athletics Federation. The track should be a pavement that meets the requirements. The altitude difference of the race route cannot exceed 42 meters. When the altitude difference of a marathon race is too large Some non-paved roads can be called mountain marathons.” Yan Yi said.

　　According to the regulations of the International Trail Running Association, more than 70% of the road conditions in the race route are "non-paved roads" before it can be called trail running. It is one of the most influential and most difficult extreme trail running events in the world, the "Ring Mont Blanc". The “Super Off-Road Challenge” (UTMB) even requires more than 80% of the “non-hardened road surface”.

In Yan Yi's view, this is the most "wild" part of the cross-country race.

　　This "wild" characteristic directly leads to extremely difficult cross-country rescues.

"Because competitions in areas far away from cities often take a long time, so there needs to be a very strict competition control system." Yan Yi said.

　　Take the Panda Super Mountain Track By UTMB after UTMB "landed" in China as an example. The event is held with an ultra-strict timing system and medical system.

For example, if the game starts at 6 a.m., according to the calculation, 80%-90% of the players should pass the first point at 8 o'clock. If the number of players actually passed does not reach this range, the system will issue an early warning indicating the existence of the game. A series of emergency mechanisms were triggered.

"At first I felt that this system was complicated and complicated, but it was really necessary." Yan Yi said.

　　UTMB was born on the Mont Blanc mountain in Europe in 2003. The track passes through France, Italy and Switzerland. It is also the birthplace of modern cross-country racing.

Yan Yi said that the weather conditions in Mont Blanc are also changing, and games are often interrupted or cancelled, but they are all based on strict pre-plans and calculations. Corresponding measures will be taken to what extent.

　　As for some people who think that not all scenic spots should be cross-country venues, Yan Yi has a different view on this.

"In fact, cross-country is an all-encompassing category of events, which is very popular. Most places, especially scenic spots, can find cross-country venues that combine their own characteristics, but it should be noted that professional organizers and experienced runners should go. Excavate."

　　In addition to stricter deployments for running races, runners participating in mountain marathons and cross-country races also need to have more comprehensive capabilities.

The marathon mainly tests the running ability of runners. In addition, they should also have field survival skills before they can participate in trail running events.

　　"Trail running events generally provide official compulsory equipment, but this is only a basic entry requirement for top players." Yan Yi said that as a contestant, you need to recognize yourself. If you are not the most capable player, you need to Based on the equipment, prepare more equipment according to your own needs.

"If you are afraid of cold, you need to bring more warm equipment on the basis of mandatory equipment; if you are afraid of heat, you need to bring more water and anti-heatstroke medicine, runners need to be in awe of the competition."

　　Yan Yi generally recommends that runners participate in the city marathon after 16-20 weeks of training. If you want to participate in cross-country running, you need to improve the outdoor survival experience on this basis. You need to know what to do if you get lost, how to deal with heat loss, and positioning You need to be familiar with the use of navigation.

　　"We often call for reverence for nature and recognize ourselves. This is not a big word." Yan Yi said that in the face of tragedy, this is an issue worthy of reflection on all parties.
