10 minutes of swimming sounds really easy when you see it on your training schedule, especially when you’ve done 20 min jogging followed by 20 min biking twice the week before.

But whoa boy, seriously.

I haven’t done more than the 5 min of lap swimming I did last week since… since… I was about 11 years old and still doing swimming lessons. Biking I do everyday, and I’m not a total stranger to jogging. But lap swimming? Damn.

I subtracted 2 units of insulin from my morning pancakes dose, which I though might be overkill because, hey, 2 units is what I kick off when I’m doing 40 minutes of cardio. But better safe than sorry, right?

I forgot that swimming is a full body exercise, and there’s a reason that Phelps eats 12,000 calories a day.

After clawing through the last of my laps, I came home and tested my sugar, expecting that I would have to do a correction.

Oh, no.

I was a perfect 95.

After only 10 minutes of swimming.

When I get up to 20 minutes I’ll be subtracting *4* units of insulin from breakfast in order to get through it. That’s pretty awesome.

I love that I can judge energy output entirely based on how much or how little insulin I have to shoot myself up with…. heh heh. My life measured in units of insulin.

So: swimming was embarrassingly tough this morning, but I got there, I did it, and the ear plugs made a big difference. As did the moment when my old swimming instructor’s voice came back to me, “Kick kick kick!” and I realized I wasn’t kicking enough. Things went much more smoothly and quickly after that.

I also need to figure out how to rotate instead of just plowing through while horizontal, which is one of the reasons why it’s so fatiguing right now. I’m wasting a lot of movement and losing my balance.

It’s been a long time since I’ve done this, seriously.
