NB35-39 Marathon: Nunez holds steady for the win

• Miguel Nunez, 4:49:50 — 1st in NB35-39, averaging 11:03/mi across 26.2 miles in San Francisco's coastal chill.
• David Hall, 5:10:32 — 2nd in NB35-39, finishing 20:42 back, averaging 11:51/mi.
• Nunez posted the 6th-fastest non-binary split on the 2M→4M segment; Hall answered with the 6th-fastest non-binary split on 6M→8M.

The NB35-39 field was a two-person battle from the gun, and Miguel Nunez made it look controlled from the start. Running at 11:03/mi through San Francisco's rolling streets and 15 mph winds, the Chicago native held his gender standing at 9th through the first half of the race before gradually slipping to 15th by the finish — a sign of the field spreading out around him, not of any dramatic fade. He crossed in 4:49:50, taking the NB35-39 win.

David Hall had a strong middle stretch, posting the 6th-fastest non-binary split on the 6M→8M segment — a genuine bright spot in his race. But the South Lake Tahoe runner, who came in averaging 11:51/mi, saw his gender standing slide from 7th to 23rd over the second half, a fade that cost him time and position. He finished in 5:10:32, 20:42 behind Nunez, to claim 2nd in NB35-39.

Nunez's own standout came earlier — the 9th-fastest non-binary split on the 2M→4M stretch — suggesting he found his rhythm in the opening miles and ran within himself from there. With cool temperatures at 59°F and a stiff breeze off the bay, conditions were as good as San Francisco offers in late July, and both athletes saw it through to the finish line.
