Crowds congregated around Bondgate Within, Narrowgate and Alnwick Castle to see some of the world’s top cyclists speed past.
Lots of shops had decorated their windows for the occasion, while red and yellow painted bikes sprung up around the town.
Mayor of Alnwick Lynda Wearn said: “It’s been a fantastic day and a fantastic spectacle. We’ve had a great crowd, a great atmosphere and it can only be good for the town to welcome such a race.”
