Bollywood celebrities, who we're used to seeing at red carpet events or high-flying bashes, left aside the make-up and put on their running shoes for the causes they support.
While some ran to support the spirit of the marathon, others attended to cheer the runners and show their complete support.
Like every year there were many stars who ran to support some or the other cause.
We saw many many B-town celebrities participating in the marathon and giving their best.
