Swimming is my biggest limiter - to state it otherwise, it offers the most opportunity for improvement. I reviewed the Total Immersion Easy Freestyle lessons on video this morning before going to the pool. I swam 1500m in under 50 minutes, with rest breaks, etc., per my planned workout. I am pleased. What pleases me more is that I caught a mistake I am making with a premature withdrawal of my arm when breathing to the left. This has been causing me to sink. I can now correct it. Reviewing the videos deepens my knowledge. I see more technique and can apply the suggestions.
Today was just trying to swim the distance. I can do this.
