It looks pretty tight. Where will discus, javelin, and hammer take place?
To my knowledge, at high-level track specific facilities, the "field" events all take place literally in the in-field of the track. They try to control the direction of the flying implements by having a large cage that surrounds the "launching" pad circle in all directions except a narrow slice that is open to the field. This hopefully prevents things like discs, hammers, etc. from flying off onto the track, into the stands, etc. Javelin on the other hand doesn't have that, but because of the way it flies and how it's thrown (the throwers run down a long runway towards the middle of the in-field), it isn't necessary. And shotput doesn't need it either, because it just doesn't fly that far.
They're centered w/rtp to the field.
You are correct, thanks. I was confused because there's an "extra" section of seating, that isn't covered, off to the side ... but appears this is due to the geometrical constraints of the space they had to work with.
