Running Robbie

Are there any other big guys around 335 pounds and rocking week 6 day 3?

I have a question....I just completed week 6 day 3. I am able to run for the entire 22 min but I'm only distancing 1.8 miles. It's up from the first 20 minute run but shy of the 2.25 the app says I should be running. Should I be focusing on the time or distance? I don't want to graduate and get to my first race and not be able to finish it because I'm not used to that distance. Should I keep repeating week 6 day 3 until I can run 2.25 miles within 22 min?
