A nod to the heat and the flags runners remember. In Chicago’s Event Alert System, yellow means moderate risk and less-than-ideal conditions. This is a name for a post-race report, not a live alert or an official race service.
Where do the rankings and percentiles come from?
We include finishers in the organizer’s Marathon runner result list, excluding separate wheelchair, handcycle and duo events. A finish-time rank is 1 + the number of runners with a strictly faster recorded finish. Equal times share a rank. “Top %” is rank ÷ group size × 100. “Peers behind you” is strictly slower finishers ÷ (group size − 1) × 100. Tied peers are not counted as slower. A group of one has no peer percentile.
The age group combines the runner’s listed gender and age division. Country means the source’s citizenship field, not residence. Organizer places can differ from finish-time ranks because of classification and timing rules. The field table preserves organizer overall places.
What can the split data tell me?
Half balance compares two equal 21.0975 km halves. The half comparison uses each finisher’s signed second-half time change: (second ÷ first − 1) × 100. The field reference is the median of those changes across all other finishers with valid halfway times. The expected second half is your first half × (1 + median change ÷ 100). The relative difference is (expected − actual second half) ÷ expected × 100. This compares pacing changes, not fitness or absolute speed. Positive means the second half took longer. The chart and table show all recorded timing mats. Segment pace is calculated between consecutive recorded mats; short segments can amplify timing or mat-position differences. Target comparisons assume an even pace across 42.195 km. Positive time differences mean behind target; negative differences mean ahead. No mile-by-mile pace or position changes are invented.
