Milind Soman's 76-year-old mother Usha Soman joined the former model in his 'The Great Indian Run' marathon between Ahmedabad and Mumbai, on the penultimate day of the run. The biochemist and former teacher ran the marathon barefoot while wearing a sari. She had earlier reportedly walked 100 kilometres in less than 48 hours for the Mumbai Oxfam Trailwalker race.
