Gillian Parrillo doesn't consider herself a serious athlete. Couch potato is more like it. But the former Sacramentan and current Dallas resident has joined two other local "women of a certain age" to participate in a triathlon -- involving cycling, running and swimming -- here this summer. It's all about supporting graduates of the Sacramento Entrepreneurship Academy. Parrillo is on the board of the group, as are her triathlon mates Michelle Hallsten and Brenda Diesel. They're being trained by SEA grad Joy Hermsen, who runs a Bay Area company that gets non-athletes prepared for physical challenges. Parrillo says Hallsten, a partner at Sacramento's Pillsbury Winthrop Shaw Pittman law firm, has high aspirations for the event. "Michelle is focused on us winning (our age group)," Parrillo says. Gillian has a different goal: "I'm focused on living to see the finish line." * * * Classy proposition: Speaking of SEA, the organization is currently recruiting its next class. Participants are mostly -- but not necessarily -- local college students. All spend every Saturday morning for nine months learning entrepreneurial basics from local business leaders. Over the past 22 years, the group has graduated 500 people. Many, like Hermsen, have gone on to found successful companies. Interested? Check it out at .www.sealink.org.
