In Tenby with the sun a shining; there were a lot more people than I expected (despite the sunny weather) then having walked into the middle of the town I found out why!
That today was the 10 hour Carten 100(miles) charity cycle ride from Cardiff City Hall to Tenby Harbour.
Around 1,800 cyclists take part; this year's ride was the 20th annual event.
Here's one of the riders crossing the finish line.
