Dawn breaks at the Sabarmati Ashram, where over a thousand people gathered to mark the 75th anniversary march's commencement.
In 1930, the Mahatma began his yatra from this ashram, which he set up soon after he returned to India on January 9, 1915 from South Africa.
Even though the Mahatma was known to walk briskly, it took him 26 days to cover the 325-km trail to Dandi. The marchers then covered an average of 14 kilometres a day, with three days marked for rest.
The march was broken into morning and evening sessions, with a long break in the afternoon. The Mahatma spoke to local people during the break.
