75-year-old Kumar is the joint opposition candidate of 17 non-NDA parties against the ruling dispensation's nominee Ram Nath Kovind.
Kumar, a former Lok Sabha speaker, will launch her campaign immediately after the scrutiny of nominations on Thursday.
Sources close to her said she is likely to start her campaign from Uttar Pradesh, which was also Kovind's first halt en route his drive to garner support for election to the Rashtrapati Bhavan.
Asked at a Congress briefing, party chief spokesperson Randeep Surjewala said Kumar was finalising her campaign and would share it "very shortly".
Kumar had yesterday made an emotional appeal to the electorate comprising MPs and MLAs to cast their vote with their "inner conscience".
She also said the President's post cannot be used for narrow political interests.
Taking a leaf from former Prime Minister Indira Gandhi's appeal made during the 1974 presidential poll in favour of VV Giri, Kumar said, "This is that moment when one should heed to the inner voice of conscience and set the course of the nation."
