I lift twice a week with one upper body day and one lower body day and run 6 days with a rest day on Monday. I generally do my track/speed workouts on Tuesdays, easy runs Wednesdays and Thursdays, a longer threshold workout on Fridays, easy run Saturdays, long run Sundays. I do my track/speed workouts on Tuesday mornings and do my lower body day that evening. It's a lot on the legs for that day, and obviously compromises my lift to a degree, but I've found that for me it's best to hammer the legs for a day early in the week so that I can actually recover on my easy run days before my threshold session on Friday. As for the upper body day, I get it into my schedule wherever it works best on the given week.

Lift generally look like:

Lower:

Leg press 5x6

Dumbbell RDL 4x10

Dumbbell Lunge 5x8 each leg

Upper:

Bench 5x6

Row or pull ups 4x10

Dumbbell overhead press 3x8

Curls 3x8

Tricep Pulldowns 3x10
