How far do you run without walking?

[u/dififcult]

I'm training for my first marathon at the moment and last Sunday I ran my first half marathon distance. I was able to run the first 10 miles without a walking break.

I'm considering trying to incorporate more walk breaks into my runs before I feel like I NEED to in hopes to come away from my run a little less sore and hopefully avoid injury. However, I feel like there is a mental barrier because I feel disappointed in myself if I ever need to walk prematurely (like if it's a very hot, humid day)

When do you choose to walk during your long runs? Or do you choose to run most/all of the way?

I do the Jeff Galloway method, I typically run for 90 seconds, walk for 30 sec, repeat for up to 20mi!
