Sheri 12. Yes!
I've copied this from the legend at the bottom of the US site program which I prefer to the UK one (why are they different I ask?!). It differentiates between pace for the run (2 mi @ 12.00) and time for speedwork (3x800 in 4:00) and spells it out (my highlight in bold).
Easy Run
Dist: 2mi @12:00 Run a total distance of 2 miles at a pace of 12 minutes per mile.
Speedwork
Dist: 5mi, inc Warm; 3x800 in 4:00 w/400 jogs; Cool Run a total distance of 5 miles. Your run should include: - a warmup of about 1 mile - 3 repeats of 800 meters each; each repeat should take 4 minutes - a 400-meter recovery jog after each repeat - a cooldown of about 1 mile
Note: Warmups and cooldowns are generally 1 mile each. But on some days, you'll need to make them longer to reach the total distance for your run.
