best program for me. make me excited to join back in sport after my operation. i always rewatch this program because ji sung and three others actors inspire me and all fans to be more active. Please continue this program, hopefully this RUNTIST will choose Malaysia as the 1 place for shooting ok. Im so excited and happy to see the ji sung spirit escpecially to do his exercise anytime. Best program i think and in another side, its show us the real personalities of our idol. Ji Sung the best!!!! keep up RUN..u will be much more healthy ok
