The camp was to end on December 31 but now has been extended by three months. The list of athletes for the camp has been shortened too.
A total of 117 track and field athletes will stay on in the extended senior national athletics camp in view of the Commonwealth Games and the Asian Games scheduled to be held later this year.
The athletics camp began on October 15 and was to end on December 31. However, the Sports Authority of India (SAI) has now extended it till March 31.
The SAI sanctioned 45 coaching and support staff for the 117 (64 male and 53 female) athletes training across five locations.
The camps are being held at the Netaji Subhas National Institute of Sports in Patiala, Laxmibai National College of Physical Education in Thiruvananthapuram, SAI National Centre of Excellence in Bengaluru, the Jawaharlal Nehru Stadium in New Delhi and Usha School of Athletics in Balussery.
The World Athletics Under-20 silver medalist and long jumper Shailini Singh, 17, was one of the eight late additions to the camp in November.
The camp also includes Hima Das and Tokyo Olympians Avinash Sable, Tejinderpal Singh Toor and Dutee Chand among others.
Long jumper Murali Sreeshankar and javelin thrower Shivpal Singh, both Tokyo Olympians, have not made the cut for the extended camp.
