BURLINGTON — Rivendell Academy sophomore Sydney Schoenbeck was second among the girls and Thetford Academy junior Ulysses Junker-Boyce was second in the boys division at the Vermont High School Decathlon Championship held at Burlington High School on Sunday and Monday.

Also registering top finishes in the field of 65 girls were Cassandra Armstrong of White River Valley (fourth) and Charlize Brown of Thetford Academy (eighth).

Junker-Boyce’s teammate, Sebastian Perdrizet, a freshman, was eighth, and Hartford senior Jordan Davis finished ninth among 68 competitors.

In the overall team competition, the Thetford boys finished second with 283 points, just three points behind winner Mount Mansfield’s 286. The Hartford boys were fourth with 248 points.

“The decathlon is a true test of one’s guts and grits,” Hartford coach Mike Perry said. “To demand so much of themselves in events they are not accustomed to and then succeed in it, I am very proud of the kids.”

Davis, with 4,972 points in the two-day competition, won the discus, javelin and shot put, with his best shot put throw ever at 44 feet, 10.75 inches, Perry said.

“He ends a great high school track and field career,” Perry added.

Schoenbeck, who was fourth last year, finished with 5,159 points, behind only North Country Union’s Sabrine Brueck (5,755). Schoenbeck was first in the high jump, second in the 100-meter hurdles, third in the javelin and fifth in both the 100-meter dash and long jump.

Junker-Boyce (5,604 points) won the 100 meters and long jump, was fourth in the 400 meters, third in the shot put and sixth in the 110-meter hurdles. Mount Mansfield’s Raf Campanile was first overall with 5,980 points.

Thetford’s Perdrizet was seventh in the javelin and eighth in the discus.

Hartford junior Bennett Moreno (11th, 4,784 points) broke his own school record in the 1,500 meters, winning the event in 4:08.42, and also placing second in the 400 meters and fourth in the javelin.

Armstrong (4,895 points) who moved up three spots in the standings in the final event with a fifth-place finish in the 1,500 meters, was fourth in the 100 meters, second in the pole vault, and third in the 400 meters.

Brown, a Thetford senior who was runner-up two years ago, finished with 4,526 points. She was eighth in the 100 meters, fourth in the pole vault, and second in the 400 meters.

Evan Rich of Thetford finished 10th overall with 4,964 points. He tied for first in the high jump and was fifth in the javelin, ninth in the shot put and 10th in the 110-meter hurdles.

Other top finishes in individual events included Thetford’s Ava Hayden (29th overall), who won the 1,500 with White River Valley’s Anya Young in eighth. Young finished the meet 24th overall.

White River Valley’s Imari Taylor was second in the discus and ninth in the javelin. Windsor’s Sydney Perry, a senior, was sixth in the javelin and 10th in the discus.

For the boys, Sharon Academy’s Zabrien McGee (24th overall) was third in the long jump and shot put, and Thetford’s Matthew Vivian (27th overall) was third in both the shot put and discus. Hartford’s Jack Fournier-Stephens was ninth in the 400, and Oxbow’s Oden Schlager was sixth in the discus.

Thetford coach Joel Breakstone said it was another solid performance by area athletes against the best in the state.

“A really impressive showing from Upper Valley schools,” Breakstone said.
