The key to running a marathon is "speeding."

The marathon is a sport suitable for all citizens and is loved by runners. According to official data, a total of 134 marathons were held in the country last year (2015) and the number of participants was 1.5 million. The marathon events held only in the first half of this year increased by nearly 2 times year-on-year. It can be seen that the people of the country approved marathons for their popularity.

However, because of the low threshold of the marathon, many runners who have just entered the ring have tried and failed to prepare for the race. This is neither advocating nor insecure. Without corresponding training, the body couldn't "eat too much" in the face of a marathon. Therefore, it is very important to run the corresponding training before the race. Especially at the beginning of the race, pace is a key point.

Speed ​​distribution usually refers to the length of time it takes to run every kilometer. It is the most important indicator for marathon runners. The speed of the match determines the finish. The pace is based on physical functions. The long-distance running of the marathon requires very high physical fitness (speed). How can the daily training be less?

Speed ​​training should follow: Speed ​​training should not exceed 10%-15% of the total training volume per week, and should be followed by stable jogging and warm-up. If the amount of weekly running is 40 kilometers, then the faster practice (such as interval and pace running) should not exceed 6 kilometers.

A sensible pace training method can greatly enhance the performance of runners; on the contrary, excessively aggressive methods may cause fatigue, injuries, and even significantly reduce the athlete's exercise life. Estimation of pace, especially in long-distance running, becomes difficult when physical strength and concentration begin to decline. Therefore, it is necessary to use a suitable smart stopwatch.

With the dual protection of GPS and acceleration sensors, the watch will remind the runners of a reasonable physical distribution through vibration, and will finish the game more scientifically and brush the PB.

In the daily training, it can independently record 5*8 hours of GPS movement data from the mobile phone. Through the operation of the watch button, you can directly view the real-time distance, pace, heart rate and other movement data.

Adhere to scientific training in order to better prepare for the racehorse, and adhere to a reasonable pace in order to make the campaign more durable.
