The possibilities are endless but here are a few suggestions:
Coaching - sell training, lessons, coaching...
Media - magazine covers, articles, ads...
Interests - hobbies, off season, charities...
Sponsors - dedicate a page or a side bar...
Blog - connect your Blog RSS feed...
Contact - text box, etc for instant feedback...
Of course, you may have other ideas, so think about anything that makes your site unique and useful to you and your audience and I will incorporate it into your website.
Rule of Thumb: Limit your navigation bar to 6-10 links.
