ご質問ありがとうございます。
ご質問について、いくつか言い方が考えられますが、例えば、
It's not just about being fast; it's about having the skills to win.
または、
Being fast is important, but skill is what wins races.
少し変えて、
It takes more than just speed to win.
どれも「単に[速い](https://eikaiwa.dmm.com/uknow/questions/60141/)だけじゃなくスキルがあってこそレースに勝てるんだぞ！」というようなニュアンスで伝えられます。
参考になれば幸いです。
