I was never a runner until I started c25k. I always tried but could never discipline myself enough to run longer than a minute or two. SO I was so excited when I ran 20 minutes straight during the training. It gets harder after that point but once you finish the training, you develop a passion for it and you can just keep going.
My advice is to keep your pace as slow as you need it to be. My jog was incredibly slow, but I was still jogging and keeping my breathing even. That's the key. Once you've lost your breath, you're done. Speed comes later.
Keep me posted on your progress! Good luck!! 1762 days ago
