Run With Me Seoul · the app
The Korean race calendar on your phone, with a reminder before entries open.
The race calendar in the Run With Me Seoul app holds 400+ upcoming road races across Korea, on a month calendar and a map, filtered by distance and by whether you can still sign up. Star one and the phone tells you the day before entries open, the thing that decides whether you get in.
Free. iOS and Android.

- 400+
- upcoming races, across 73 cities and regions

How the race calendar works.

01
Open the month and see what is on.
Every race in the country on one month calendar, a dot on each race day, that month's races underneath. Tap a day, or switch to the map for what is near you.

02
Filter down to the ones you could actually run.
Chips for 5K, 10K, half and full, for races taking entries now, and for the ones you starred. Search by name across every month, not just the one on screen.

03
Open a race and get the facts without the pop-ups.
Date, distances, entry fee, cutoff times, start venue and the organizer's own link. Korean race sites bury the price three clicks behind a wall of banners. This is that page, flattened.

04
Star it and let the phone watch the date.
Star a race and the app warns you the day before entries open, and again just before the opening hour where the organizer publishes one. Popular Korean races sell out in minutes.

Who it is for.
You keep running past races you did not know about.
Ten thousand people on your normal morning path and no idea it was happening. That is what started this. The races are not hidden, just scattered across a hundred sites.
You find the race two weeks after entries closed.
Korean races open and fill fast. The entry window is the only thing between you and the start line, and an alert beats a calendar you remember to check.
You do not read Korean.
Race names, venues, regions and distances are in English, with the dates and fees pulled out of Korean organizer pages so you do not have to.
You are building a season.
A half in October needs a plan made in June. A year of dates tells you which races fit around each other.
What it is not.
The race calendar does not take your entry.
The app sends you to the organizer's own site or Instagram, and you register and pay there. No entries, no payments, no fees taken by me.
It is not official, and it is not sponsored.
Nothing here comes from a deal with a race. It is public information, collected and checked. No race paid to be in it or to sit at the top.
Most next-year dates are not confirmed yet.
124 races carry a date the organizer announced. The rest are next editions placed in the month they land every year, and the app says so on the race rather than in small print.
It is not the browsing version.
Comparing the big autumn marathons, working out what the JTBC weekend is like: that is what the race pages on this site are for. The app is the calendar in your pocket, with the alarms.
How it fits with the rest of the app.
- The race calendar on the web
The same database, a page per race and room to write about them. Read there, get alerted in the app.
- Run tracking
The race you starred counts down on the same home screen as this morning's run.
- Curated Seoul routes
A race in October wants long runs in August. The routes are the part that gets you there.
Questions.
Where does the information come from?
Organizer sites, race Instagram accounts, registration platforms and the Korean race calendars, pulled into one database and checked by me. For 111 of them I open the organizer's page myself, on a rota, the only way to know a date is real.
Can I trust the dates?
Trust the 124 marked confirmed. The rest are next editions placed in the month they land every year, and the app says so on the race. Nothing here invents a date and presents it as fact.
Can I sign up in the app?
No. It opens the organizer's own registration page. Your entry, your money and your data go to the race, not through me.
What exactly will it tell me about registration?
A notification the day before entries open, and another just before the opening hour where the organizer publishes one, because the popular races are gone in minutes. Mark a race as one you are running and you also get race eve and race morning.
What happens when a race is cancelled?
It leaves a note. A race that drops off the calendar shows as cancelled or postponed, so one you starred cannot go missing without you being told.
Something is wrong. Can I tell you?
Yes, and this is the part other calendars do not have: a person reads it. quintin@runwithmeseoul.com.
Stop finding out two weeks late.
