Races/Singapore
Training plan for the BYD Singapore International Marathon – Half Marathon
Saturday, 5 December 2026 in Singapore. That is 2 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:
Half — a 14-week build, 4 runs a week
Not enough room left for the full build.
Too close? The next one
The organiser runs this the first Saturday in December, which puts the 2027 race on Saturday, 4 December 2027. That date is not announced yet, so check it before planning to it — but a Half build for it would start the week of 23 August 2027.
On the day
One distance: Half. Entries, course and timings are singaporeinternationalmarathon.com’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.
