Almost 5,000 riders have taken part in the Gran Fondo cycling event which started at Belfast's Stormont estate.
The mass participation cycling event is a legacy of the Giro d'Italia - part of which was staged in Northern Ireland in 2014.
Now in its third year, the two-day event has grown in popularity - attracting record numbers.
The race is split into two separate routes - one through Strangford Lough, which is a leisurely 36 miles.
The other is a more testing run to the Mournes in County Down, and back, which clocks in at just under 110 miles.
Stormont also provided the finish for this year's races.
Ass Chief Const Alan Todd said: "I want to take this opportunity to thank everyone who took the time and effort to come out and support the cyclists who were taking part in this event."
He also congratulated everyone who was involved in making the event a "success".
All the roads which were closed to allow for the event have now re-opened.
