Well done! That all sounds good
Those last 50m are tough at the end of the session.
Good job on the underwater kick set
Somethings to keep an eye on: Make sure you are pointing your toes, If you have stiff ankles work on stretching them to give you more flexibility. Think about lifting your hips toward the sky when swimming and make sure you are exhaling all the time when your face is in the water (blow bubbles). All of these have the side effect of drag. If you hold your breath it causes the chest to rise and the legs to sink. If your feet are not pointed then they stick down and cause drag. Lifting the hips can help raise the legs.
Continue also to think about the catch phase of the stroke. Check this out and applie it to the side kick drill.
