Los Angeles Orienteering Club
O'Neill Regional Park 2026
O'Neill Regional Park, Trabuco Canyon
Sunday, January 25, 2026
After a series of rain delays at O’Neill Regional Park, we finally had a beautiful day of orienteering. We had 107 individual participants and an additional 16 Teams. As we were unable to go off trail in hills, there was a white course and 3 distances of yellow. Do not be fooled. The course may have been navigationally intermediate, the hills were grueling. Luckily, they afforded the runners grand views and opportunities to see all sorts of animal life and early season flora.
White: Wayne Cottrell has been putting on the jets lately and came in first on White with Isaac Barocio the first junior, Team Kosters Klub the first team, and Madeline Malas the first female (junior).
Short: Charlotte Lee from Troy won the Short course, followed 1 second later by Russel Thiem. Representing SDO, Susan Tischler was the first woman coming in on Short.
Medium: Aarush Pathak from Troy had another good day, dominating the middle course, with Polina Biryukova coming in as first female. The middle course had a lot of Teams with Team I Don’t Like the Woods getting props for their cute name and coming in as the first Team.
Long: The long course was a family affair with Mikhail beating out his dad, Sergey, for first. And Olga Urbanovskaia edged ahead of Vladislav Urbanovskiy to place as first woman, and Team Orientals Squared were the first Team to come in on the long.
