The headline story in M40-49 was a tight two-man race at the front. Mark McDermott, 47, from San Rafael, crossed in 40:58 at 6:36/mi to claim the win — a sharp effort in cool, lightly rainy Santa Rosa conditions. Right on his heels was Aleksandar Naumoski, 45, of Hayward, finishing in 41:06 at 6:37/mi. Eight seconds separated them after 6.2 miles — a margin that speaks to how closely matched these two were, with Naumoski's pace just a tick off McDermott's throughout.

Caleb Guest of Petaluma rounded out the podium in 41:34 (6:41/mi), 28 seconds back from Naumoski. Behind him, Ever Merida (Madera) was solid in 4th at 42:05, while hometown runner Christopher Morrell (Santa Rosa) and David Park (also Santa Rosa, 40) kept the pressure on, finishing 5th and 6th in 42:49 and 42:57 respectively. Leonardo Naves, Jason Knight, and Randell Hansen rounded out the top nine, all finishing between 43:10 and 43:39 — a remarkably tight cluster of seven men across just 90 seconds from 3rd through 9th.

The race then fractured sharply. Tyler Jeppson in 10th clocked 46:25 — nearly three minutes slower than Hansen's 9th-place 43:39 — marking a clear divide between the lead pack and the rest of the 66-man field. Further back, Ryan Nubla (47:13) and Raul Negrete (47:16) were separated by just 3 seconds in 12th and 13th, while David Santschi and Miguel Arbulu both stopped the clock at 48:46 to claim 15th and 16th. McDermott's 6:36/mi winning pace set a high bar on a damp August morning — one the top nine alone came close to matching.
