Thanks.

Hill repeats are mixed into my Long Run. I wasn't very clear on that, sorry. I have a hilly section about 2.5 miles from home that's a little over a mile long with 4 hills. I run over, and do 3-6 passes through the hills, charging up the hills and recovering on the backside. Then extend the run out to 2 hours.

If you've got a favorite 5k/10k pace workout...let's have it. I like structure, and I like structured progressions. Eg, one I've done in the past:

wk1: Warm-up then 2 miles at 10k followed by a set of 3 x 800M at (15s faster than 10k) and 3 x 800M at 10k.
wk2: Warm-up then 3 miles at 10k followed by a set of 2 x 800M at (15s faster than 10k) and 2 x 800M at 10k.
wk3: Warm-up then 4 miles at 10k followed by a set of 1 x 800M at (15s faster than 10k) and 1 x 800M at 10k.
....
Repeat above dropping pace by 15s.
