The Full Form of RCR is Race Course Road.

7, Lok Kalyan Marg (formerly 7, Race Course Road) is the official residence and principal workplace of the Prime Minister of India. Situated on Lok Kalyan Marg, New Delhi, the official name of the Prime Minister’s residence complex is Panchavati. It is spread over 12 acres of land, comprising five bungalows in Lutyens’ Delhi, built in the 1980s, which are the Prime Minister’s office, residency zone and security establishment, including one occupied by Special Protection Group (SPG) and another being a guest house. However, even though there are 5 bungalows, they are collectively called 7, Lok Kalyan Marg. It does not house the Prime Minister’s Office but has a conference room for informal meetings. The entire Lok Kalyan Marg, which lies right across the road, is closed to the public. Rajiv Gandhi was the first Prime Minister to reside at the erstwhile 7 Race Course Road, in 1984.
