Am I too old to start competitive gymnastics again?

I am 13 (almost 14). I did gymnastics for almost 7 years. I was in the TOPS program and I was in Level 7 when I stopped. I lost alot of my flexibility and strength and cant do the splits all the way down anymore. But I can still do alot of the skills. I can still do flip flops, kips, and cartwheels on the beam. I would like to compete competively again and i know its not really a possibilty but go to nationals or the olympics one day. Will I be able to compete at a high level again or am I too old?
