Heartland Series Day 5

Heartland Series Day 5 takes place on July 14, 2027, in Clinton, Iowa. 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.

By the fifth day of a series, the body has usually adapted: soreness plateaus and a strange, steady rhythm sets in. That is also when runners make their mistake and race — resist it. Iowa in mid-July is humid from dawn, so the day's real work is drinking enough between races rather than pushing the pace during them.
