Why do Muslims run in the middle of 2 hills Mecca?

Muslims don't run between hills in Mecca. There seems to be a misunderstanding here. The city of Mecca hosts rituals and rites as part of the annual pilgrimage known as the Hajj, including performing the Tawaf, which involves circling the Kaaba, a sacred building in the center of the Grand Mosque. However, there is no practice or ritual that requires Muslims to run in the middle of specific hills in Mecca.
