I swam 3136m today, in the PC 32m outdoor pool. Started at 14:30. Sunny, warm. Pool was 27 C.
512m (8 laps) warm up.
12x 192m (3 laps) Descending tempo (with TT) per repeat, hold SPL.

In the 32m pool, 22 SPL is about 16.5 SPL in a 25m pool.
I had to work to hold the SPL. I was pumped at the end but not exhausted.
I experimented with the recovery arm swing and entry point to see if I could find a more relaxed stroke. When I recovered narrow and targeted a bit shallower (straighter forward rather than angling down), and hugged my shoulder to cheek I could get a bit more glide, but it cost me in energy consumption- just a lot more muscle strain involved to hold that position rather than use a wider swing, and more relaxed spear hand and lower target. To do the latter I would add 1+ to the SPL – but over a long distance it would be worth the energy savings to use this wider swing and more relaxed entry and reach to target.
