That's probably what I will say when I finish a 5K, but today I said it after jogging for 3 minutes straight. When I started I could only jog for 15 seconds at a time. The couch to 5K program starts with intervals of jogging 60 seconds and walking 90 seconds, so I had to create 3 levels before that of 15, 30, and 45 seconds.
This new year, I knew I still wanted to train to run a 5K, but I needed to keep it low impact until I get under a certain weight. I don't think my shins are made to handle the force of this much weight jumping. I decided to go with a "jogging" pace of 4 mph. True, many people can walk this pace. It's a really awkward pace for me, but it's the fastest I can go without leaving the ground. My heartrate goes all the way up and I have to push myself to do the intervals, so I guess it's enough.
At my new pace, I've been able to keep going 3 days a week for 6 weeks now. My progress feels slow sometimes, but I felt a huge high today from the progress I did make!
