To express "跑步" in English, the correct term is "running." It is pronounced as /ˈrʌnɪŋ/ (RUH-ning). This word can be used in various contexts, such as jogging for exercise or sprinting in competitions. For example, "I go running every morning" translates to "我每天早上跑步." If you're referring to the action itself, the verb form is "run," as in "She likes to run in the park."

To practice the pronunciation, break it into two syllables: "run" (like the sun) + "ing" (like the ending of "sing"). Common phrases include "running shoes" (跑鞋) or "running track" (跑道). Remember, consistency in practice will help master both the word and the activity!
