So I just got done with day three of the challenge. And for day four it says walk/run or cycle. Is it ok to take up a running program along with this? Or should I just alternate? (Walking for 90 sec/jogging for 60) during the whole challenge? Cause I was debating of fitting in a c25k on the walk/run days
