Greyhounds took to the new £1.8m track at Towcester Racecourse for the first time - the first track to open in the UK for 19 years.
More than 35,000 cubic metres of soil were delivered to develop the state-of-the art circuit ahead of the first races on Wednesday.
The 420 metre track features banked turns and the latest technology, including non-shadow, LED flood-lighting.
The only other venue in the UK to boast such lighting is Stamford Bridge, home of Chelsea Football Club.
Owners put the track through its paces when time trials began over the soft sand of the circuit but the first greyhound race meeting will take place on December 6.
There are further meetings scheduled for Friday and Saturday nights in the run up to Christmas.
