#5 — 1A Boys 2026 Week 8
Won the JAC Invitational on Saturday in 16:29.1 out of 85, 3.1 seconds ahead of Elijah Parkinson of St. Augustine, with Olson fifth. Sixth in the Bale-N-Trail Elite race on September 26 in 16:06.1, a week after 16:02.8 at the adidas championship in North Carolina. Up from seventh: he has not raced Arterburn or Barton, and his season figure is now ahead of both.
#7 — 1A Boys 2026 Week 7
Did not race. Sixth in the Bale-N-Trail Elite race on September 26 in 16:06.1, a week after 16:02.8 at the adidas championship in North Carolina.
#5 — 1A Boys 2026 Week 6
Sixth in the Bale-N-Trail Elite race on Saturday in 16:06.1, a week after he ran 16:02.8 for 35th at the adidas championship. Twenty-third at the Horse Park in 16:23.7, behind Barton and ahead of Manderson. Up one, to fifth.
#6 — 1A Boys 2026 Week 5
Did not race. Twenty-third at the Horse Park in 16:23.7, two places behind Barton and four ahead of Manderson, after 16:33.0 for 46th at Cecil Field. He beat Kirwan at Cecil Field, 46th to 50th, and that result holds him above his Circle Christian rival until they meet again. Sixth for a second week, and the first man on a Cornerstone Classical team that is third on the team list.
#6 — 1A Boys 2026 Week 4
Did not race. 16:33.0 at Cecil Field and 16:23.7 for 23rd at the Horse Park, two races ten seconds apart on the clock and four apart leveled. Sixth, up one place without racing as Domico dropped, and the best runner on the fourth-ranked team in the class.
#7 — 1A Boys 2026 Week 3
Ninth in 1A at state in 16:22.1, 16:33.0 at Cecil Field and 16:23.7 at the Horse Park. Same pattern as Barton one place up: two fair courses, a little better the second time.
#4 — 1A Boys 2026 Week 2
Ninth in 1A at state in 16:22.1, 16:33 at Cecil, and quiet since. Nothing has changed for Kline, which in a week where three new names crashed the bottom of this list is its own kind of result. He holds fourth on the third-best returning mark in the class and a perfectly normal opener.
#4 — 1A Boys 2026 Week 1
Ninth in 1A at state in 16:22.1, third-fastest returning mark in the class, and 46th at Cecil in 16:33 — ten seconds off, which is a normal opener for a runner in shape. No drama in either direction.
Kline is a junior on the third-ranked 1A team, and the interesting thing about Cornerstone is that he is no longer clearly their best runner.
