Hi!
Im 15 years old, and i run twice a week in school, but, if i breakfast before the run(20 minutes before) ill get dizzy when starting to run.... and if i dont eat, the ill get tired.... what should i do!!!!!!!!!!!!!!!!!!!!!!!
Wake up earlier and eat. Eat smaller ammounts before and after the run. Or develop some higher cognitive abilities to think a little more about the situation and possible solutions.
Eat some good carbs and solid food about 2 hours before you run, then try to pump some water and fluids into your system, within the last 30 minutes before running, just keep your throat wet and you will be set
