The bold is why you're not getting results.
Shorter, less frequent bouts of interval-style and/or high intensity cardio should replace the distance runs. 2-3 sessions/week is plenty.
Heavy strength training is just as important while dieting as it is while attempting to gain weight. "Light weight toning" isn't much more than glorified cardio; without a stimulus to retain muscle, you don't change body composition, you just become a "smaller fat person" (not saying you're fat, just using an analogy). Full body workouts with compound exercises in the 5-6 rep range are what's called for, again 2-3 times/week.
FOr your weight, BMR is somewhere around 2300-2600. Shoot for the low end and drop another 20% off that, for around 1700-1800 cals/day. One gram/lb of body weight of protein, 75-100g of good fats (fish oil is a must, nuts and nut butters, olive oil are good choices), and the rest for "good" carbs.
For you I'd shoot for ~160g protein for 640 cals, 85g fat = 850 cals, and 100g carbs.
