SF Marathon Half: Sheyner rules M40-44 in a sub-7:00 tour de force

• Gennady Sheyner won the M40-44 race in 1:31:52 — a 7:00/mi average that left the field nearly four minutes behind.
• Brian Yee and John Leu staged a thrilling late charge, finishing 2nd and 3rd just five seconds apart (1:35:36 vs. 1:35:41) — Yee's closing leg was the 41st-fastest finish split among the women's field, while Leu had done his damage earlier on the 2.2M–5.7M segment.
• Carlo Segala (4th, 1:36:36) arrived fresh from the same weekend's Saturday 5K, where he'd placed 5th among the men — a genuine two-race feat worth noting.
• The top nine finishers all came in under 1:38:46, then a gap of more than three minutes opened before Zachary Fong crossed in 10th at 1:41:52.

Gennady Sheyner, 42, from Menlo Park, was simply in a different race. His 1:31:52 — averaging 7:00 per mile through San Francisco's famously hilly streets in cool, humid 54°F air — put him nearly four minutes clear of everyone else in the M40-44 field. His moves tell an interesting story: he surged through the men's field early, then drifted back slightly through the middle miles before reasserting himself. His 2.2M–5.7M split was the 36th-fastest among the women's field, a marker of just how hard he was pushing through that stretch. By the finish, the gap to second was decisive.

Behind him, the race for the podium was a genuine battle. John Leu, 40, of San Francisco, was the more aggressive early mover — his gender-place tracking shows a gradual drift backward from 58th to 79th across the race, meaning he ran the front half strong and held on. Brian Yee, 43, traveling from New York, did the opposite: he started deep in the field (194th among men at the first checkpoint) and reeled in runner after runner, finishing with the 41st-fastest closing split in the women's field. He caught Leu with almost nothing left — five seconds separated them at the line, with Yee in 2nd at 1:35:36 and Leu in 3rd at 1:35:41. Their average paces were both listed at 7:18/mi, but Yee earned his place with a back-half surge; Leu faded just enough to let him through.

Carlo Segala rounded out the top four in 1:36:36, a 7:22/mi effort — and deserves a second mention for having already raced the Saturday 5K earlier in the weekend, finishing 5th among the men in that event. David Ishikawa (5th, 1:36:53) and Gianfranco Rabaroza (6th, 1:37:17) kept the pressure on through the top half of the leaderboard, with eight athletes finishing inside 1:38:00 in a competitive M40-44 field of 203.
