Races/Japan
Training plan for the Tokyo Marathon
Sunday, 7 March 2027 in Tokyo, Japan. That is 16 weeks away.
When a build would have to start
OLTRA 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 March, which puts the 2028 race on Sunday, 5 March 2028. That date is not announced yet, so check it before planning to it — but a Marathon build for it would start the week of 25 October 2027.
On the day
One distance: Marathon. Entries, course and timings are marathon.tokyo’s. They decide when entries open and close, and whether the race runs at all — OLTRA 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.
