How have you counteracted added body weight in your running routine?

as a Pose running coach, I recommend learning how to run. your weight will affect your run, but not as much once you understand how to move better. Is there a HAWC on your base? They may have a Pose coach or at least someone who can give you pointers.

Regardless of weight, I found that interval speed training helps cut times down effectively. I hover between 225 and 240 and my 2 mile run times only fluctuate by 30 seconds. I usually conduct 1/4 mile tempo runs up to 4-6 miles and when I go to run my 2 miles for a time, my lactate threshold is not even close to being met although I've increased speed and pace for the entire two miles.

You should be proud of you efforts.
Most lose weight during cardiovascular activities. I would think you need to adjust your diet but not sure how to recommend.
Do you use a protein powder supplement?
