There will also be triple jump, high jump, shop-put and javelin contests and a 3000m walk.
Mr Harris said the A race over 1500m - Willis' specialist distance - was being aimed as a race that would attract an exclusive field in the hope of posting a fast time.
The inaugural meeting will not double as the track's official opening, though.
Mr Harris said that will come later. Whereas the prospect of beginning athletic events on January 12 was "quite cool", things would be even better when the hammer cage and discus cages were ready, he said.
This week volunteers have been constructing the hammer cage, which is in itself no mean feat. The volunteers had to dig 17 holes over a metre deep and 50cm wide in extremely stoney ground to put down the foundation for the cage.
