Dry heaving/ gagging

Question
Hello!

Im a 13 year old boy and a freshman on the xc team. I am 119lbs and 5 foot 2. Our training consists of regular 4-6 mile runs at an easy to a moderate pace and track workouts,tempo runs,hills, and long runs. We also incorporate stretching and drills. Everytime when i race whether its an 800m or more i tend to dry heave in the middle to the end of the race. It really slows me down and is painful. This will also happen when we are doing a track workout when i go faster than normal.Sometimes in a race when im not even pushing myself hard i can feel the dry heaves coming and then it happens I do not know what im doing wrong i hydrate and eat 30min before i run. How can i stop the dry heaves? Is there anything that i can take before I run a hard effort so i dont end up gagging?

My theory on this is that i think i get too nervous before a race and that somehow causes me too dry heave during my peformance.

Thank you so much for taking the time out to read my question
