Pacing and effort are eluding me in swimming. Today I was supposed to get progressively faster every 100m through a 600m set and repeat that 3 times. In the first and second sets I managed to take a very few seconds off across them but the general picture looks as though I maintained the pace. Now that's maybe a step forwards as in previous time trials I've started too after and slowed. By the third set I knew I was tired so cut that short. I couldn't get a single length below a 2:30min/100m pace.
My final few lengths without the pull buoy were horrendous and showed how much I'd tired as I needed 50% more strokes to do a length than I had in the warm-up.
