Good thing today was a swim workout. The problem is that when you go from nice cold dry air, into the pool, the water feels like really warm treacle. Did a good warmup, going a bit longer than the plan, just to be sure. In fact it's odd, I was trying to cool down a bit so the water would feel cooler. I swim better in cooler water.
Then into lots and lots of 50 m intervals. I learned something today. It's much harder doing 50 m intervals by yourself, than doing them chasing cute Jenna toes, and trying to avoid being caught by Tish. Especially when the pace clock is essentially invisible, and the second numbers on my waterproof watch are really tiny. But that went really well. Flip turned most of it, and I think I'm getting the hang of it. It's tough watching the surface go by a few inches up, while your lungs are wanting some air. I did some very ungraceful surfacing.
Made up the rest of the hour with medium speed swimming thinking about technique, and working on the turns. Then into the dive tank for another hour, starting with 15 minutes of core, 30 minutes of deep water running, then another 15 minutes of core.
Then out into the still very cold.
