About
Heartland Series Day 3 takes place on July 12, 2027, in Portage, Indiana, on the third day of the series. Four distances are offered: the marathon (26.2 mi), the half marathon (13.1 mi), a 10K (6.2 mi) and a 5K (3.1 mi). Start times are not listed in our records.
Day three is where consecutive-day racing stops being a novelty: muscle soreness peaks around forty-eight hours after the first effort, which lands exactly here. The runners who complete a full series treat every day as a long easy run with a number on, eat within twenty minutes of finishing, and save any racing for the final day.
