In the pool. Hours every day.
Why? Because I have a plan. Part of that plan requires me to swim a marathon plus next week.
I have ceased all running and all cycling for the last two weeks because of the plan. After the plan, I will have a life again. It will be sad if my plan does not work, but I will be able to bike and run, one way or the other after next week. I will probably read a book or play the ukulele or watch TV or something else.
The plan sucks. But, it is the plan.
