This is a basic swim programme taking swimmers from "Can Swim" to "Triathlon Ready" over 8 weeks of 3 sessions per week, with complete video backup.
The plan is supported by YouTube videos on the SwimCycleRunCoach channel and the Triathlon 101 Playlist, (that can be accessed from this link https://youtu.be/e7u9HVOvzAE) where all the drills are explained and demonstrated and all the sessions are explained, so you are going to the pool fully prepared.
There are test within the programme so you can check your progress.
If you can't do 3 sessions per week then you can simply extend the time you take to complete the course.
