"I already feel different," the gold medalist, 53, told PEOPLE just after his sunset nuptials to paralegal Chaillot, 52, at Geoffrey's in Malibu on Oct. 12. They shared their big day with 160 guests, including Olympians Janet Evans and Nadia Comaneci, and Barbara Eden and French Stewart.

"It's been an incredible journey, and we have so much more to look forward to."
