Stage winner was British ride Lewis Askey after more than 180km of racing through the north of the county, taking in Market Rasen and Caistor on their way.
Spectators decorated homes and businesses and cheered on the riders as they whizzed through the streets and country lanes at amazing speeds.
Caistor put on a great show with numerous painted bicycles and banners on display thanks to a band of volunteers and supportive local business owners.
They finished with five circuits of Lincoln and five climbs of the famous Michaelgate, before the race came down to its final metres on Newport.
From the Lincolnshire Wolds to the streets of Lincoln, thousands of people came out to watch, cheer on the riders and be part of a fantastic day for the county.
