Plan Description

A 12-week off-season plan for beginner triathletes who want to build a better base before the next race build.

This programme combines manageable swim, bike and run work with simple at-home strength and conditioning. The aim is to improve consistency, movement quality and general endurance without rushing into race-specific intensity too early.

It is a good fit after a season of racing or before your first structured triathlon build. You will develop useful habits, build strength where it matters and give yourself a stronger platform for the work to come.
