M55-59 Half Marathon: Walter Martinez Wins Chicago 13.1 in a Front-Running Battle

By MyRace AIJune 1, 2025Official site ↗
  • Walter Martinez took the M55-59 title in 1:23:52 (6:24/mi), edging Bob Geiger — who finished in 1:24:07 — by just 15 seconds after the two ran nearly stride-for-stride through the back half.
  • Both Martinez and Geiger cracked the top 200 among women by the finish, with Martinez closing at 155th and Geiger at 163rd in the women's field — testament to how fast the top of this age group ran.
  • The gap from 2nd to 3rd was a chasm: Niall Cullinane crossed in 1:28:42, more than four minutes behind Geiger.
  • Jack Fleming (Natick, MA) was the lone out-of-state podium contender, finishing 4th in 1:29:06 — just 24 seconds off Cullinane despite fading through the second half.

Walter Martinez and Bob Geiger turned the M55-59 race into a two-man time trial. Both men were running in the 200s among women at the gun and spent the entire race reeling in competitors ahead of them. Martinez moved from 198th to 155th in the women's field across those checkpoints; Geiger tracked almost identically, going 203rd to 163rd. The 15-second margin at the line tells the whole story — these two were inseparable until the very end, and Martinez simply had a little more left.

Behind them, the race took a very different shape. Cullinane held steady through the middle miles and delivered the 266th-fastest split among women on the 15K-to-finish leg, enough to secure third comfortably. Fleming, meanwhile, was actually running ahead of Cullinane at the 10K mark — his gender place was 292nd to Cullinane's 334th — but Fleming faded while Cullinane surged, and the 24-second gap at the line reflects that late-race reversal.

Fifth through the rest of the 195-finisher M55-59 field spread out across a wide range of paces. Mickey Weibeler came home 5th in 1:33:56 (7:10/mi), more than four minutes behind Fleming, and the next cluster — Wasik, Pearson, Vazamim, and Smith — arrived in a tight band between 1:35:33 and 1:38:10. On a clear, mild Chicago morning with a 10 mph breeze, conditions were about as good as this race gets, and the times at the top reflect it.
