I'm not running to enter a 5K or anything, but I've only been running since June 3rd and I just completed my first 5K, is that normal progression?

I run .7KM - 1KM 5 times a week on my lunch break(5 minute drive away), and did a 2K and 3K before this 5K. I rest on my first day off before the bigger runs.

I wasn't even tired at the end of the 5K. Had to keep going for a bit just to get back to my house. Haven't brought any water or taken breaks yet.
