Santa Rosa Half Marathon M40-49: Arriola Edges Out a Sub-1:12 Battle at the Top

• Randy Arriola (41, Scottsdale) wins M40-49 in 1:11:16 — a 5:26/mi clip through morning mist, holding off Kevin Pool by 23 seconds.
• Pool surges late: Pool moved from 20th to 14th among men on the 7M→Finish stretch, posting the 12th-fastest split on that segment in the men's field — faster than Arriola's 15th-fastest — but couldn't close the gap entirely.
• Fernando Cabada (43) claims 3rd in 1:14:21, a full 2:42 back of Pool, leaving the podium well-defined.
• 191 men finished in the M40-49 field, with the top 20 all breaking 1:30.

Santa Rosa delivered a cool, misty morning — 56°F and near-total humidity — and the conditions suited the front of the M40-49 field just fine. Randy Arriola of Scottsdale ran 5:26/mi to claim the win in 1:11:16, a commanding performance that held up even as Kevin Pool made a forceful move in the back half. Arriola had slipped from 7th to 10th among men through the middle miles, but his early bank was enough; Pool's late charge — climbing from 20th to 14th among men on the 7M-to-Finish segment — was the faster closing split, yet the 23-second deficit was simply too much to overcome. Pool finished in 1:11:39, a strong 5:28/mi effort that earned him a clear 2nd place.

Fernando Cabada (43, Aurora, CO) rounded out the podium in 1:14:21 at 5:40/mi, finishing 2:42 behind Pool and also moving up the men's field on the closing stretch. Behind him, Robert Nation (4th, 1:17:50) and John Ferguson (5th, 1:18:23) were separated by just 23 seconds, making for the tightest battle of the afternoon outside the top two. Alan Thong (6th, 1:19:01) closed out a clean top six before a noticeable gap opened to Sergey Vasyliev in 7th at 1:22:03.

The depth of the M40-49 field at Santa Rosa was real: all 20 listed finishers broke 1:30, and 171 more crossed the line behind them across 191 total finishers. Arriola's 1:11:16 stood as the class of the group, but the race within the race — Pool hunting him down over the final miles and nearly, but not quite, getting there — gave the M40-49 story its sharpest edge.
