There's no single “better” race — it depends on what you want out of the day. Marine Corps is prime bq course (forgiving course, some friction); Tokyo is prime bq course (forgiving course, very high friction). Here's who wins by goal.
| If your goal is… | Pick | Why |
|---|---|---|
| A fast time / Boston | Tokyo | flatter course, cooler typical morning |
| A first marathon | Tokyo | more forgiving on debut day |
| Easiest entry | Marine Corps | less lottery / qualifier friction |
| Crowd & support | Tokyo | bigger field, more on-course energy |
| Lower trip cost | Marine Corps | 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.
