Springfield Marathon - Harvest Wind Half Marathon & 10K

Springfield Marathon - Harvest Wind Half Marathon & 10K runs at Danenberger Family Vineyards in New Berlin, in Sangamon County, on November 7, 2026. The marathon (26.2 miles), the half marathon (13.1 miles) and the 10K all start at 8 a.m., with the marathon and half held on USATF-certified courses.

The marathon is a Boston qualifying course, so this one is aimed at runners with a number in mind; awards go to the men's and women's fields and across age groups. Chasing a qualifier means working backward 16 to 18 weeks from race day, anchoring each week with a long run and spending regular time at goal marathon pace. The half is the natural pick if you want the same certified setting over a shorter distance, and the 10K closes out the program.
