I regularly participate in mini-marathons (as they are sometime unofficially locally called) that happen around my area. I started with 5 KM and over a couple of years have improved my distance to 10 KM. But this is still not what a marathon or a half marathon would constitute.
I want to write about my interest in running on my resume/website. What would be appropriate?
I am a runner.
I am a mini-marathon runner.
I am a long-distance runner.
Or something else, as the distance doesn't seem to be sufficient for it to be related to marathons or long distance running.
