Sunday’s Garmin Run Marathon Series Singapore at Marina Barrage goes ahead on 25 October in a shortened form because of the haze. Garmin Singapore has cancelled the competitive category and cut the 21km to the 10km route, under the haze contingency plan the organiser drew up with guidance from the National Environment Agency and Sport Singapore.

What changes on race day

  • The competitive category is cancelled. Registered competitive runners can still run on a non-competitive basis.
  • The 21km is shortened to the 10km route and flags off at 5am.
  • The 10km category is unchanged and starts at 6am.
  • The Race Village stays open until 12pm, along with the booths and activation areas.

Collecting race entitlements

All participants can collect their race entitlements. Runners who finish the 10km route collect theirs at the finish line. Those who choose not to run collect at the finish line recovery zone or the Race Village, from 7am to 12pm on Sunday.

Why the race was shortened

Garmin’s plan ties the race format to the one-hour PM2.5 band. In Band 1 both races run as planned. In Band 2 the 21km moves to the 10km route. In Band 3 or 4 both races are cancelled. The shortened format now in force is the Band 2 option.

At 6am on Saturday, NEA’s one-hour PM2.5 readings were 72 to 115 across Singapore, all in Band 2, and the 24-hour PSI was 112 to 139, NEA data on data.gov.sg showed at 6.15am.

Health advice for runners

Garmin Singapore strongly advises people at higher risk, including pregnant women, children and those with chronic respiratory or cardiovascular conditions, not to take part in outdoor or strenuous activity. Participants are strongly encouraged to wear a face mask, and masks will be provided at the finish line recovery zone. Runners who feel unwell should stop and seek medical help.

Under NEA’s general advice for unhealthy air, healthy people should cut down on prolonged or strenuous outdoor exertion.
