The routes for various categories at this year's Standard Chartered Marathon Singapore (SCMS) on Dec 7 will merge only over the last 500m, after organisers introduced revisions to free up more space for runners.
The 12,000 participants in the half-marathon will experience the biggest changes.
Last year, the 21km runners shared 3km of their route near the finish line with those in the 10km race and marathon, prompting concerns about congestion.
This time, the half-marathon runners will get off the Marina Coastal Expressway to head to Maxwell Road at the 18km mark.
They will make their way through the Central Business District, via Robinson Road, Collyer Quay and Anderson Bridge, before finishing at the Padang.
Participants in the 10km and marathon categories will continue taking the route that uses Republic Boulevard, Raffles Avenue and Esplanade Drive before arriving at the same finish line.
"Feedback from participants has always been very important for us to continuously improve the race experience," said Chris Robb, chief executive of race organisers Spectrum Worldwide.
"While SCMS accommodates runners of all abilities, a key priority for us is to provide an outstanding experience for our long distance runners. It is this group of runners who will benefit the most from the new route change and we're very pleased to have found an effective solution."
With the alterations, runners will also be able to run close to and take in the sights around the Singapore Sports Hub.
Runners in all categories will continue to be flagged off in waves from their various start points to avoid crowding at the outset.
Those who sign up before midnight will avoid paying a $20 late fee, and can also personalise their race bibs. About 54,000 runners took part in last year's edition.
