I'll probably go riding again tonight (25 miles would be nice), because the weather is supposed to be crappy tomorrow and Saturday. I'd much rather take a rest day when it's raining than when it's sunny and 70.
In any event, I don't know how ready I'll be for the duathlon, but I'll probably attempt it anyway. The biking will be easy. The running could kill me. Of course, the corporate challenge is 2 weeks after that! I am scheduled to run 30 minutes on Saturday. I'll be interesting to see how that goes.
Despite all this, I actually feel pretty darn good, physically anyway. My percent body fat is going down. Hopefully my blood pressure is too (I should check), and I'm actually losing weight. Fancy that!
