Please help! Something about cross-country. I need an answer before tomorrow!?

My school is having a cross-country programme next tuesday and i need to hand up my form tomorrow. The problem is, i simply can't run, or walk, long distance. i don noe why, but i don have asthma, epilepsy or anything. So, i am forced to go. I don wan to, cause everytime i run or walk for long distance i will faint, get dizzy, and i can't breathe. i need a very good reason to skip it and i have to go on that day to get full attendance. and if u go but don run, you can be the teacher's helper. i don wan anything to happen to me that day, it will really be awful for the whole sch to see me faint. don suggest stamina exercise, it doesn't work on me. So any good advice? i really need to explain to my teacher, but wat shall i say? i daren't take the risk. The whole point is: i don wan to run (walk), but i don have a good reason, so i'm stuck in the middle. What shall i do? Many people in my school doesn't run, for they lie to the teacher about having some diseases, but i don wan to lie!

Have you tried explaining about your dizziness to the teacher? Just tell them what normally happens, surely they'll have some sympathy.
