The 2026 Garmin Run Marathon Series Singapore will decide at 11pm on Saturday (24 October) whether Sunday’s race at Marina Barrage goes ahead, is shortened or is cancelled, based on the one-hour PM2.5 reading at that time under the organiser’s haze contingency plan. The race has 21km and 10km categories.
The timeline
- Saturday 24 October, 5am: organisers began monitoring the 24-hour PSI
- Saturday 24 October, 11pm: decision to proceed, shorten or cancel, based on the one-hour PM2.5
- Sunday 25 October, 4am: monitoring continues, with hourly updates on Garmin’s social media channels
Runners can also join a WhatsApp haze community for updates.
What each band means
