In jan '09 I decided to step it up and start running after having been a powerwalker for about 6 years. I sued the couch to 5k podcast to get into it. I probably ran about every second day for about 25-30 mins depending on my energy levels. Although, I generally can't run the whole time in one go, as I have bad knees and I am suited to sprinting, not long distance.
In late December '09, I decided to step it up again and I have started running with 1kg weights. It's bloody hard, I can tell you! But hopefully, it will be rewarding in toning my arms, burning more kjs and increasing fitness.
