Besides the main 25km race, which will be flagged off at 6.30 am, the Rs 22.80 lakh event will be held across three more categories of Senior Citizen's Run (4km), Champions with Disability (4km) and Ananda Run for 5km.
The starting and finish points of all the events will be at the Red Road and about 10,000 runners from different walks of life are expected to run in the wintry Sunday morning.
Keen on winning the Mumbai marathon for a fourth successive time, Lalita will be running the 25km race for the first time and will look to take it easy.
"I just ran the Delhi Half Marathon 20 days ago so there's little time to recovery. I've not set any target here... The focus is on Mumbai (January 17)," Lalita, an Asian Games 2014 bronze-medallist and the reigning Asian Championship 3000m steeplechase winner, said.
