Doubts

I'm having doubts about this whole running thing. I had done two weeks of the couch to 5k training on the Treadclimber, but it only went 4mph. I started the training from the beginning when we got a regular treadmill. I'm doing the walks at 3.5 and the runs at 5mph. I didn't have any problem doing the intervals in weeks ones training. I just finished the first day of week two and I thought the extra 30 seconds of running was going to kill me. I may be walking the 5k, we'll see.
