I'm not sure if you're saying this as somebody who never runs, or somebody who runs so often that you've forgotten baseline levels. That's a very significant hurdle for most people. I'm in very good shape strength wise, but I'd almost certainly need to do some significant training to meet that since I just never run.

I run for weight loss and general health and at one point had a BMI in the mid-thirties. Back then I was able to make that pace for sessions of 30-40 minutes on most days. I'm not suggesting it's easy, but I would expect someone in ICE to easily outrun an obese person.
