sacred ways from badaling

Do you mean the Sacred Way in Ming Tombs? You can just visit the sacred ways there and ignore the tombs. From Badaling, you can take bus no. 919 to Changping Xiguan, transfer to bus no. 314 to ming tombs. It takes over 1 hour. From ming tombs, you can take bus no. 314 to Changing Xiguan, transfer to bus no. 919 or 345 to Deshengmen, changge to bus no. 380 and get off at Huizhongli to take bus no. 417 to olympic site. I think one day is not enough to visit Badaling, the sacred ways of ming tombs and olympic site if you will travel with the public transport on your own.
