Answer: Running volume, speed, power
Explanation: For marathon training, running volume is always a topic that cannot be avoided. If there is no running volume that meets the standard, there will be no standard endurance, and there will be no way to complete the race. However, the way to improve endurance is not only to increase the running volume. A long distance run is also very important. For the marathon, long-distance running has many advantages, and the intensity is basically in the category of easy running. From a spiritual level, long distances can help runners to increase their confidence, and help runners to enhance their endurance and movement stability during the race. As an excellent runner, running volume alone is not enough. With speed training, the training system will be more complete. The speed training we are familiar with is intermittent running, also called repeated running.
