Is it really necessary to only do this type of workout only a few days a week?
I am Wk 6 of CT5k with my next workout day being Friday. I am thinking as long as I don't go all out on the jog intervals it should be fine. I have some of the podcasts that coach you through short walk/jog intervals varying form 30 sec to 1 min for either a 30 min or 45min workout. I would like to use these on the days I don't do the longer runs with CT5K and take 1 full rest day a week.
Opinions or advice. Thanks
