Welcome. I am quite new here and consider myself new to cycling. Rode regularly, out of necessity,ages 10-24 then bought a car. So now in my 40's back at it. It's a great way to get fresh air and see sights. College can be quite stressful, and biking is a good stress reliever also. You definitely need to eat enough to fuel your body. My story is different in that I have lost 116 lbs. And have to stay mindful to keep it off.
Anyway welcome.
