48 weeks to race day: base season

Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured 12-week block starts later; what you do now decides how high it can climb.

“Wales does not do flat, and Swansea is no exception. Treat this as a hill race with a swim in front of it and gear accordingly.”

The race

Swansea gives you the Welsh coastline at 70.3 distance. The swim is in the bay, sheltered but still open sea. The bike heads onto the Gower peninsula, an Area of Outstanding Natural Beauty that earns the name with the climbing to match. The run returns to the flat seafront, which is a relief your legs will have earned. Pair it with Tenby in September and you have a full Welsh season.
