NB35-39 Marathon: Nunez holds steady as Hall fades late

• Miguel Nunez, 1st in NB35-39 — 4:49:50 (11:03/mi), posting the 9th-fastest non-binary split on the 2M→4M segment
• David Hall, 2nd in NB35-39 — 5:10:32 (11:51/mi), finishing 20:42 back after a significant fade in the back half
• Hall ran the 6th-fastest non-binary split on 6M→8M — a bright mid-race moment that couldn't offset what came later
• The 21-minute gap between two finishers tells a tale of two very different second halves

In a two-person NB35-39 field on a breezy San Francisco morning — 59°F, 15 mph winds, and 77% humidity — Miguel Nunez of Chicago ran a composed, consistent race to take the win in 4:49:50. His 11:03/mi average held together across the full 26.2 miles, and his 9th-fastest non-binary split on the 2M→4M stretch showed he was moving with real purpose through the early miles.

David Hall of South Lake Tahoe came out with energy. His 6th-fastest non-binary split on the 6M→8M segment was a genuine highlight — he was rolling through that stretch with some of the sharpest non-binary runners on the course. But the gender-place tracking tells the harder story: Hall moved from 7th to 23rd among non-binary runners by the finish, a slide that began around the halfway point and kept going. That's not a stumble — that's a prolonged fade over the back half of the marathon.

Nunez, meanwhile, slipped from 9th to 15th among non-binary runners overall, a modest drift that speaks more to others finding another gear late than to any collapse on his part. He crossed in 4:49:50, Hall in 5:10:32 — a 20:42 gap that ultimately made the NB35-39 outcome clear well before the finish line.
