Tips for cross country? I'm currently a high school sophomore in the socal area and I just joined the cross country team at my school. I've been a runner since elementary school,  but never got the chance to join the team until this year (packed schedule). 

I run in the B group, and I think I'm doing pretty good in it, but I always have trouble with my lungs and never my legs. Is this the same for most runners? Also any tips?
