The rising Kodiak High School senior placed seventh in the 5,000-meter run at the New Balance Nationals Outdoor track and field championships on Saturday in Greensboro, North Carolina.
Thomet clocked a time of 14 minutes, 40.44 seconds in a field that featured 22 of the top high school runners in the nation.
Alex Osteberg of Darien, Connecticut won the race in 14:16.61, and was the only runner to finish under 14:20.
Thomet consistently ran laps between 1:10 and 1:12 and had a fast lap of 1:06.90.
Galen Rupp — an Olympic silver medalist and American record-holder in the 10,000 — holds the national high school boys 5,000-meter record with a time of 13:37.91, which he set in 2004 as a senior at Central Catholic in Portland, Oregon.
Before the meet, Thomet spent six days attending the Naval Academy Summer Seminar program in Annapolis, Maryland. He was one of 2,550 people selected to attend the seminar.
In late May, Thomet became only the third boy in Alaska history to win state titles in the 800, 1,600 and 3,200. He was also a member of the winning 3,200 relay team.
