Most of the established stars will be missing in action but thousands of other athletes, including the up and coming ones, will get the platform to make a mark in 32 disciplines when the 38th National Games, spread over seven venues in the hill state, begin in Dehradun on Tuesday with the official opening ceremony. Prime Minister Narendra Modi will declare the Games open at the Rajiv Gandhi International Cricket Stadium to kick-start the 18-day national showpiece, which will see participation of around 10,000 athletes and officials from 38 teams. In terms of sheer number of athletes, the event is among the biggest in the world, though its relevance in the country's international success has been debatable.
