'Make-up' workouts can be scheduled at ANY time. If no one is meeting you at the pool, they won't know you weren't there, right?
Be flexible. If the fam wants to do something with you in lieu of your short run, put the short run off for another day. Maximize your time with them while you have it.
If you get rained out from your group ride, stay with your group (they need your support), just go get beer instead and food if necessary.
Clean the house, it may not get done for another three weeks or so. AT LEAST until your next recovery week.
Swallow your pride and use the week as recovery - you don't need to PROVE anything to the fat guys smoking in their cars as you run down the road. If you're supposed to be zone 2, stay zone 2.
Watch disgusting amounts of TV while you can, including a series marathon of ANY kind. My arse was meant for a sofa...stupid bike seat.
Good luck to anyone racing! I hope you're dry, I'm drowning in it over here.
