I’ve looked it up and I haven’t found anyone using this term in the same way I use it today. I’ve found definitions ranging from a wild radish to some World of Warcraft term. But I have a completely different definition for this term …
RUNCH
I have decided to runch four times a week. What is that you ask???
Instead of sitting at lunch, eating too much, with toxic people, I going running.

Then I stop for a tea bomb at the nutrition tea/shake place.
I’m running about 1.5 miles with 80% of that running and 20% walking (panting/dying).
It has been amazing for my mental health and physical health in so many ways.

I’m so very glad about that! I’d never heard of the word, but your definition makes more sense than any other.
