After graduating a couple of months ago I've been out running 2 or 3 times a week for 30 mins at a time. Today, I felt different (no idea why), so I challenged myself to cover the full 5K, which I hadn't achieved yet.
I did it, not that fast, but I got there. It took me just over 36 mins and I feel great! Going to stick with this distance for a few weeks then gradually increase. I've discovered that running is quite addictive! I love it.
