I really want to find a writing contest...

I'm 50 pages in to my story, and have a feeling it won't get published. But, I still want my work to go to use... so does anyone know of a writing contest for teens (through 13 or 13 and up) where you can enter a fiction story of at least up to 70,000 words? I'd prefer one that's not... weird, or suspicious, and one that isn't for adults (too hard of competition). Thank you!
