Races/South Korea
Training plan for the JTBC Seoul Marathon
Sunday, 1 November 2026 in Seoul, South Korea. That is 3 weeks away.
When a build would have to start
ALLUNGO plans a block of a length that suits the distance, then works backwards from race day. For this one:
Marathon — a 18-week build, 5 runs a week
Not enough room left for the full build.
Too close? The next one
The organiser runs this the first Sunday in November, which puts the 2027 race on Sunday, 7 November 2027. That date is not announced yet, so check it before planning to it — but a Marathon build for it would start the week of 28 June 2027.
On the day
One distance: Marathon. Entries, course and timings are en.marathon.jtbc.com’s. They decide when entries open and close, and whether the race runs at all — ALLUNGO sells nothing here and takes nothing from them.
The date here is the one the organiser published, rechecked every 1 hour against the list. Confirm it on their site before you enter.
