Hi! I just started Xtrain 90 day undulating program today. I usually have one day of running a week (about 5-8kms) I would still like to continue running though so it's not super hard to get back into it! How can I incorporate running into the rotation? I don't want to do two workouts in one day. I was thinking of running as the first day of each week and then follow the program for 5 days, one day off...continue with the program adding a run day here and there. What is everyone else doing?
