Congratulations! I remember the first time I was able to run a 5k on the treadmill without walking. It is such a great feeling and no small feat. I know a lot of people who run often who still struggle to finish a 5k without walking. Great job!!!

On a side note- I found it much easier to establish a base cycling than running. I am not sure what the difference is, but it sounds like you now have a very solid base for running.
