An out-of-state White Sox fan put her mark on her first Chicago Half Marathon on Sunday. Becca Prichard of Boulder, Colo., held on to win in 1 hour, 19 minutes and 10 seconds, beating Becca Thompson of Houston by 10 seconds.
In his first in Chicago, Abdelaziz Atmani of New Augusta, Ind., outpaced the men’s side in 1:06:03, beating Greg Costello of St. Louis by nearly two minutes.
‘‘I started on pace,’’ Prichard said. ‘‘Things went great for the first 11 miles, then the wheels came off.’’
The half marathon follows 13.1 miles on the South Side, primarily along south Lake Shore Drive, beginning and ending in Jackson Park.
Prichard, who was using this as a tuneup for the Chicago Marathon next month where she hopes to do a 2:46, arrived from Colorado on Friday, then went to a ballgame with her dad, Paul, a Sox fan from South Carolina.
‘‘It was pretty hot today,’’ Prichard said. ‘‘I poured water on my head at every [water station]. Friday night, it was cold. We had hot chocolate at the White Sox game.’’
Sunday morning was different: 66 degrees, bright sun and light winds.
‘‘It was a little bit warm, but I am used to it,’’ said Atmani, who had two runners pacing him the first three miles, then held pace to win easily. ‘‘It is a beautiful flat course.’’
Most famous of the nearly 20,000 runners in the Chicago Half Marathon and Karhu 5K was champion speedskater Apolo Ohno.
‘‘My initial instinct is to hammer the first mile,’’ said Ohno, who resisted that and finished in 1:40:59 in his first half marathon.
‘‘It was beautiful,’’ said Ohno, who’s training for the New York City Marathon. ‘‘I live in LA. This is perfect weather.’’
Jean Marinangeli of Schaumburg was the highest finisher of local runners with a third (1:20:05).
