Wii Running

I didn't make it outside for a run today because I was determined to get all of the laundry done. Not the best of excuses but if you had seen the mounds of laundry just waiting and begging to be washed you would understand. I'm almost done with the laundry and now it's too late to go out for a run. I did run with the wii fit today. I did the island lap for the first time. I've determined it is a lot harder to run in place for 12 minutes than to be moving forward. My legs were killing. I guess a little workout is better than no workout. Any one know how long the island lap is suppose to be on the wii fit??
