That's the idea! Start out with something like Veronica suggested, like light spinning or an easy swim - maybe some rollerblading or volleying of the tennis ball. These easy days will ease the guilt you have by at least doing something and the fun you have with the tame workouts will fuel your fire for the harder ones. Just be patient, ramp up and avoid burnout. To tell you the truth, I feel guilty every single day that I'm not active, but if it was for a good reason (ie. needed rest or quality time with family/friends, etc.), the guilt quickly subsides to justification.

Sounds like you've caught the tri bug - it's a great ride!!!
