Video: Gran Fondo - A great day of racing for thousands of cyclists
Over 3,000 professional and amateur riders signed up for the two races.
The first cyclists pushed off at Titanic Belfast at 7.30am on Sunday and covered 173km around the Mourne Mountains in Co Down.
They arrived back at the finish line in Belfast after midday, while those racing the shorter distance of 58km around Strangford arrived earlier in the morning.
The top honours of the day went to local cyclists Mark Kane and Chris McKeown.
