Ok. Let's just make it clear what your goals are. Your goals are to have visible abs which for most people means losing enough bodyfat to ....well, have visible abs.
This is important to define because far too many people work out without a clear idea of the path they need to take to reach a goal. Thus they train and eat haphazardly, usually making very little progress.
So, with your goal in mind, a few things need to be done:
1)Follow an eating program conducive to fat loss.
2)Strength train to maintain your current muscle mass. If you're lucky, and do everything right, you might gain a little bit, too.
3)Use your running as your energy systems work for additional fat loss.
Excellent! Congratulations on overcoming that, and continue to stay on top of it.
Hate to break it to you, but most folks around here do not recommend such long-duration running when trying to achieve a lean, muscular, physique. It tends to be too detrimental to maintenance of muscle mass. However, I think if you don't overdo it you'll be fine. You're are going to have to make sure your caloric deficit isn't too great so that you don't burn up too much muscle tissue.
I personally think that is too much, especially if you are trying to lose the remaining bodyfat you have hiding your abs. If you are in the gym that often I don't see how you'll be training intense enough. Physiologically, you're going to need some off days where you do nothing intense.
Both seem like good plans. For the amount of aerobic work you are doing a highER-carbohydrate diet would probably benefit you more than a low carb approach, and carb cycling could combine the best of both worlds. On your off days you could try going low carb, higher fat, and then cycle your carb amounts based on your activity levels. Berardi style is awesome, too.
My final thoughts are to:
1) Pick a calorie level.
2) Split up your macronutrients accordingly.
3) Set up a moderate running schedule.
4) Set up a three-four day a week strength routine centered around heavy lifting in the core exercises such as the bench press, military press, squat, and deadlift variations and try to maintain or gain strength on those lifts in the rep range you are working at from week to week. Add in accessory work a couple of days a week, too.
You sound like you've got a good grasp of things, just realize that the amount of running you do, although you like it, may not be the optimal way to achieve the body you want at the moment. But if you're in decent shape this should not take forever, and then when you reach your goal you can reevaluate and pick a new goal and go from there.
Best of luck.
