For Japan's track and field athletes, Sunday’s Seiko Golden Grand Prix will be an important chance to check out the track, grass and pits at Tokyo’s National Stadium ahead of next summer's Olympics.

The 10th anniversary event, which was originally scheduled for May 10 but postponed by the COVID-19 pandemic, will take place at a brand new facility that will be used as the main venue for the Summer Games.

But the meet, which is part of the World Athletics Continental Tour, will be held behind closed doors.
