Does anyone here have access to detailed information on year-over-year differences in elevation gain, or course maps for the years 1996-2001 and 2003-2005 for the Chicago Marathon? <\/p>\n
I am working on a research project to understand how air pollution impacts physical performance. We are using Chicago marathon race results (1996-2022) combined with EPA air pollutant data to understand this. To ensure we provide accurate estimates, I want to control for a few things.<\/p>\n
Elevation gain:<\/strong> Most sources state that the course has a 74m elevation gain. However, the course does change a bit over the years and this elevation gain estimate does not seem to be updated. Furthermore, on Strava Chicago marathon segments there is a high variation in what the elevation gain is. <\/p>\n Course maps:<\/strong> I’ve managed to find and digitize maps from 2002 and from 2006 onwards using GIS. I used these maps to estimate elevation gains using USGS elevation data, but my results are showing much higher elevation gains (around 300m in total), which seems off. <\/p>\n I reached out to the Chicago Marathon organizers but they responded that they didn’t have any of this data and that all of their memorabilia was lost in a flood. The Chicago Tribune doesn’t appear to have a lot of easily searchable information for the earlier years either. <\/p>\n Any help or pointers to resources where I could find this data would be greatly appreciated. <\/p>\n Thank you for your help!<\/p>\n<\/div>\n submitted by \/u\/supermooseslay <\/a>
