There's no single “better” race — it depends on what you want out of the day. Chicago is great first half (forgiving course, some friction); Life Time Miami is great first half (moderate course, low friction). Here's who wins by goal.
| If your goal is… | Pick | Why |
|---|---|---|
| A fast time / Boston | Chicago | flatter course, cooler typical morning |
| A first marathon | Chicago | more forgiving on debut day |
| Easiest entry | Chicago | less lottery / qualifier friction |
| Crowd & support | Life Time Miami | bigger field, more on-course energy |
| Lower trip cost | Life Time Miami | cheaper all-in from South Florida |
Cost and travel are estimated from South Florida; your own origin may flip the trip-cost row. Full method on the methodology page.
