Wanting to gain weight, but I also like running...any suggestions?

If you wanna gain weight and build muscle running will definitely not help you at all. I'm the same way, in my case to stay healthy I HAVE to gain weight pretty much and running was my favorite,I use to win every race in middle school and high school but I had to stop and never even run anymore,you seem like a pretty good weight to me, but I think if you cut down your schedule a little bit and in between have resting days where you drink protein shakes then your goal will be accomplished. Remember drinking a protein shake will add weight THEN working out will turn that weight into muscle!
