Good to update. ### 2/5 — Runners details map is poorly executed. *2025-10-12* Runners details map is poorly executed. The x axis has the incorrect units and says miles when the graph is actually is tracking kilometers. Also why is the y axis decreasing? This is not helpful for the visualization and outside of convention. Who made this? Where was the QA? ### 2/5 — What year is it? *2025-10-12, version 13.1* This app looks like it was made in 2013. Is this really what TCS wants to show potential customers? ### 2/5 — Sort of functional *2024-10-13, version 12.0* The app’s tracking feature is decent, but not very trustworthy. Other than that, there aren’t really any things about it that make it deserve a good rating. There’s no way to switch to miles, it’s incredibly glitchy, and very outdated and not up to the standards it should be. ### 1/5 — The Chicago Marathon needs to get rid of this app! *2023-10-10, version 11.2* The app is poorly designed and not very friendly. Most importantly it did not provide real time updates and alerts on runners. Chicago needs to use the same apps as other Marathons (like Marine Corps). I realize TCS is a sponsor, but this is a prime example of the poor quality you get from them. ### 1/5 — Worthless app *2023-10-08, version 11.2* Worst app I’ve ever downloaded. Not a single button on the entire app did anything. I got over 20 attempts with the same result: “cannot connect to server. Try again later. “ No tracking, no nothing. Couldn’t enter a bib number. I should’ve expected nothing less from anything associated with Chicago, the rectum of central USA. ### 1/5 — Overseas user *2023-10-08* Was able to get the information about course etc from app but all live data such as leaderboard and tracking was an error of ‘could not connect to server try again later’. Luckily family members sent text messages to keep me up to date. ### 2/5 — Barely functional enough to avoid 1 star *2023-10-08* No way for runners to truly claim a profile, defaults to kilometers with no way to convert to miles, live tracking not very functional, no way for trackers to share real-time messages with runners, and no (easy) way for runners to access messages sent. And it wasn't even released until 3 days before the race. Expected much more from the official app for a world major ### 1/5 — An embarrassment *2023-10-08, version 11.2* A mess of an app who’s day-of-race performance was deeply unhelpful. ### 1/5 — horrible *2023-10-08, version 11.2* i want to see inly a few things. a map with : the mile markers in miles, the route, where the bib i’m tracking along the route is, the start and finish points, the cta el stops near the route. the end. hate the corporate sponsor logos, cheer spots and the other crap on this app. ### 1/5 — Cannot connect to server *2023-10-08, version 11.2* Get server errors for any of the icons I try to click on. ### 1/5 — Horrible app *2023-10-07, version 11.2* App doesn’t work and keeps freezing ### 1/5 — Can’t track anyone *2023-10-07, version 11.2* I admit to having an old iPhone, but the iOS is version 16 so it’s still should work. However, I am unable to track anyone. What is up with that? ### 1/5 — “Cannot connect to server” *2023-10-05, version 11.1* This is the only thing I see when clicking on any of the icons. What’s up with this app? ### 1/5 — KM vs MI *2023-10-05, version 11.1* Will there be an option to swap between miles and km? ### 1/5 — Couldn’t even find it *2023-10-04, version 11.1* Thanks for not even putting the name of the actual event in the name of the app ## Most critical reviews (10 lowest-rated) ### 1/5 — Awful app *2025-10-13* The map tracker should be geared towards spectators. The mile markers would sometimes appear and it was hard to find what mile our runner was at. The map showed the water stations… I’m sorry but runner is watching the map while they run. It needs to be geared towards the spectators trying to find their specific runner. ### 1/5 — Horrible *2025-10-12* Horrible. App doesn’t update times Links in map doesn’t work. Basically a waste of time ### 1/5 — Won’t connect to server *2025-10-12* Terrible app, doesn’t even work. ### 1/5 — Useless app *2025-10-12* On race day still shows timer indicating the race is a day away. Can’t track racer - times out every time I put in their bib number. ### 1/5 — Why? *2025-10-11* Why make me update? I downloaded the app yesterday ### 1/5 — Embarrassing *2024-10-13, version 12.0* They mixed up miles and kilometers and the pace graph is based on minutes having 100 seconds ### 1/5 — Miles tracker *2024-10-13, version 12.0* This app needs to track distance by miles in addition to kilometers. Lots of Americans run this race. ### 1/5 — 2024 version *2024-10-13, version 12.0* No mile markers this year making it incredibly difficult to track runners. Disappointed in the quality ### 1/5 — Cannot connect to server *2024-10-13, version 12.0* The only information this app ever gave me. ### 1/5 — TERRIBLE APP *2024-10-02, version 12.0* my husband and i are trying to get this downloaded and ready for his race 1.5 weeks away. every single time we log in, it gives us an error. how can i trust that this will track him correctly on race day?? boston marathon app was amazing compared to this. i guess we will just use his garmin share. ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2025-10-13, version 13.1* Used the app in the U.K. to follow my daughter and her partner. It was excellent.

Chicago marathon is the best, very well organized. ### 5/5 — But I have a *2023-10-07* Be safe and let me know ### 5/5 — Picture *2022-10-10* It was a very useful app for watching my friend run the race. I would have liked a end of the race picture at the finish line. A picture of him crossing the finish line. That would have made the experience complete. ### 5/5 — Great for Race Day *2022-10-10, version 10.2* Great for tracking friends and getting your own splits. My friends were able to track me in real-time, which was super cool. Nice to be able to add people that I met to the tracker. ### 5/5 — So many cool features *2022-10-09* Loved being able to watch top American leader boards, track my favorite runners, AND actually see them moving in the map! I could actually send a personalized cheer card to my favorites. Best Marathon app I’ve used. ### 5/5 — Loved following my friends *2021-11-15, version 9.2* Worked great to track my friends. Very cool! ### 5/5 — Tracking my friend - Great *2021-10-11* (1) The setup procedure was quick and easy (2) The tracking map was spot on. It had my friend tracked that we had no problem spotting him and cheering him on. (3) I was able to switch the map from Ks to miles A special thanks to the developers of this app. ### 5/5 — Easy to navigate! *2020-10-11, version 8.1* Easy to download and navigate through each setting.
