Beginner runner here, question about cycling + running I enjoy running and cycling on alternate days; my question is about whether I HAVE to also incorporate weight training. At this point, i'm just trying to get to the point where I can jog around 30 - 40 mins without stopping. So would biking 3 days a week + running 2 days a week while slowly increasing the intensities be enough to get me to that point?  


Thanks for all the replies everyone!!
