You might want to check with your doc on the stitches. I've heard it isn't recommended, and many public pools don't want people with wounds in them. I'd think you'd want it to be sealed/covered, too -- and chlorine does kill off new skin cells and can slow the healing of skin, so be careful of that, too. If it is only another week I'd say you are safe to just wait for a week. Just make the next week a bike or run focus and get in a few extra workouts there. You have time... no worries :)

Oh and thanks for the great job note :)
