8.3 miles in three legs; swim 1,000 meters; walk Inga.
I know a single kilometer at a time is nothing in distance, but it's long enough for me concentrate on my new technique, on kicking harder, and on breathing every other stroke. I'm down to every 1.8 strokes, say. I really must learn to do a proper flip-turn. Also I can do a pretty reliable 20-minute kilometer now, and have set myself a goal of a 30' 1500.
