Runner's World reported on October 7, 2026, that Jacob Nur, 71, is returning to the Chicago Marathon to pursue the 70-74 age-group world record of 2:54:18, set by Haeng-cheol Shin in Seoul. The report said Nur ran 2:59:01 at the California International Marathon in December and has adjusted his training, cutting weekly mileage from 70 to 60 miles and reducing hard workouts from four to three. A later Runner's World report on October 8, 2026, listing notable entrants for the 2026 Chicago Marathon, again noted that the 71-year-old Nur targets the 2:54:18 age-group world record, alongside Anthony Rizzo's marathon debut and Des Linden's race three weeks before the Javelina Jundred. Coverage remains limited to these two reports, both previewing the attempt rather than reporting a result; no conflicting accounts of Nur's times or records appear in the supplied reports.
Anthony Rizzo will make his marathon debut at the 2026 Chicago Marathon, running for his family foundation, with former Cubs teammate Jake Arrieta joining him. Des Linden races the World Marathon Major three weeks before the Javelina Jundred, while 71-year-old Jacob Nur targets the 2:54:18 age-group world record.
