I started the timer after my walking warm up and just as I started the interval run (though more like interval slow jog in my case but I am 262 pounds working my way up to a run). Just shy of 2 miles, so I will try to run slightly longer to get to two miles. My goal is to run a full 5k by the end of the summer (if not earlier in the summer). Is it best for me to keep doing two miles until I can run it all the way through at a decent pace (what pace should I aim for?) or should I add distance once a week while still doing intervals or something else? I welcome any web site/reading recommendations as well. Thank you.
