What racers and reviewers say
- RaceRavesRaced 2026 · aggregator · Mixed
93 ratings (47 marathon), 3.9 overall; difficulty 2.5, scenery 3.6, production 3.8. Runners love running through Churchill Downs; many call it flat and PR-friendly except Iroquois Park. Complaints: sparse neighbourhood crowds, aid shortages, bib and result mix-ups, unreliable RaceJoy tracking, poor start toilets, and warm humid years.
“Mostly flat and suited to PRs.”
- MarathonGuideRaced 2023 · aggregator · Positive
Single review, 4.0: enjoyed Churchill Downs and a pedestrian bridge into Indiana, a decent expo and nice shirt, but her watch read 26.66 mi (42.9 km) and other runners lost Boston times to the long course; long walk back to hotels.
“Fun marathon! Fast course but long.”
- Felix WongRaced 2026 · blog · Positive
3:31 finisher. 15 °C (59 °F) overcast, humid but fine. Bugle start, tunnel past Churchill Downs near mile 11 (18 km), Iroquois Park rollers that broke up the 3:30 pace group, warm crowds, wave seeding with some runners moving forward. Course measured 26.5 mi (42.6 km) on Strava.
“Southern hospitality is not a stereotype.”
- Maniacs Fanatics MadnessRaced 2022 · blog · Mixed
Half marathon report. Flat course past Churchill Downs with horses warming up, crowds sparse but enthusiastic and bigger at the finish, nine water stops. Criticised expo signage, a long shirt line, toilets crowding corrals, and no gear check signs. One-time race for her.
“decent and pretty flat”
- Marathon Training AcademyRaced 2012 · blog · Mixed
Marathon recap: Churchill Downs tunnel and infield, shaded Iroquois Park with hard climbs in miles 11 to 14 (18 to 23 km) and another set in miles 21 to 24 (34 to 39 km), plentiful aid, ideal cool overcast weather, poor division of the road where half and full courses merged around miles 18 to 21 (29 to 34 km).
“Every marathon has its own personality.”

Local runner argues Iroquois Park hills are modest, most rising only about 15 m (50 ft) with downhills in between, but criticises a course change that left marathoners isolated after the split near mile 8 and merged slower half runners late.
“Iroquois is no Eden Park hill in the Flying Pig.”
- Spectrum News 1Raced 2026 · article · Positive
2026 race-day coverage: over 10,000 runners from 50 states, start before sunrise at Slugger Field, and runners praising neighbours who came out of their houses to cheer and a fun start.
“they come out of their houses”
