Not enough ECs?

<p>Hi, I'm a junior right now, so I still have some time to change things, which is why I wanted to ask you guys.
So I have a 4.0 gpa, and about 2210 SATs (221 on PSAT). I'm pretty worried about my extracurriculars though. I've done varsity cross country, swimming, and track+field every year so far. In sophomore year, I joined a tutoring club at lunch, and the french honor society. This year, I'm doing tutoring, Key club, french honor society, and NHS. I also worked as a lifeguard this past summer, and plan to next year; and I have been on a summer swim team for 11 years.
When I compare this to the records that people on here have, I really feel like I'm lacking a lot of ECs. I'd like to apply to a top tier school, and this is naturally worrying. Am I right that I need to do more?</p>
