December 31, 2025,Run along Cardiff Bay

Beautiful day for a final run in 2025. Happy New Year! ❤️🎉

November 30, 2025,Cardiff Bay - Wintry Run

This became an out and back as the bridge was up and never seemed to come back down 😀 There was a tall-masted boat underneath there and it didn't seem to be moving.

Mystery - but was a great excuse to run back along the Barrage separating the sea from the bay. My favourite place ❤️
