Can Mantz and Sisson set American records on Sunday at the Chicago Marathon

Conner Mantz and Emily Sisson are looking to set American records at the Chicago marathon on Sunday.  Mantz, who comes to his marathon debut with impressive XC and track credentials, has his eye on Leonard Korir’s American debut mark of 2:07:56, which was set in Amsterdam in 2019.

“All of my races and workouts have led up to this distance,” Mantz said. “I get excited thinking about it but I need to remember my first marathon and there are some unknowns.”

Sisson, who set the American women’s record in the half-marathon with a 1:07:11 at the USATF Half-marathon Championships in Indianapolis in May, only has one completed marathon under her belt – a 2:23:08 at London in 2019 (she dropped out of the 2020 Olympic Trials)– but has her eyes on the women’s American record of 2:19:12, which was set this past January by Keira D’Amato in Houston.

“My first marathon experience was really positive, and I really enjoyed it,” Sisson said. “After my first marathon in London I was drawn back to it and really want to see what I can do.

“My main goal is to try to break 2:20. If I’m feeling good and the record is in striking range I’ll take a stab at it. I had a really good buildup without any big setbacks. The weather for the weekend looks great, and I don’t know how many times I’ll have that, so I might as well take a swing at it.”

The temperatures will be in the low-50s at the start of the race and most likely cross the 60-degree mark by the time the men’s and women’s winners will cross the finish line. While it may be a touch humid at the beginning of the race, that isn’t expected to have that much of an effect.

Even more promising is the wind. Chicago is unique among the World Marathon Majors in that much of the course up to the halfway point is run in the core of the downtown area among the tall buildings, which can whip the wind around. It also leaves the potential for the competitors to be dealing with a headwind as they make the final push up Michigan Avenue to the finish.

This year, the predicted 7-12 mph winds will be from the southeast, which could be a bit of an assistance over the final few miles.

The race is set to start at 7:30 AM Sunday, and will be shown locally on NBC and streamed on Peacock.
