Running twice a week. Seeking advice.

Hey all.

I'm currently running twice a week (the other days I rock climb and lift). in those 2 days, I do an easy run and either a tempo run or intervals.

A couple of questions:

1. what would you say is the best use of my 2 days of running?

2. if I were to add a 3rd day, would the best approach be to do easy day, tempo/interval day, and a long run?

I appreciate everyone's input. I understand 2 or 3 days might not seem serious, but rock climbing and lifting are my main priorities. That said, I have been enjoying running quite a lot (being an absolute hater before) and I would like to continue improving.

Again, thank you all for your advice.
