Am I the only one who can't hit Threshold pace on the evening after 5-6miles easy in the morning?

Imagine that you are running with soneone else and actually say a few words. If that was too hard, then you are going too fast.

So wrong it's not even funny. By that definition marathon pace is LT. The best way is to test you max heart rate and then run as close to 90% as you can. It will be much closer to your actual LT than your talking method described above. And it will be much faster, too.

Another good rule of thumb is to add one minute you your current mile race time. A 4:30 miler would run about 5:30 and so forth.

No. Rhodo guy is right and you are wrong in the dismissal of his post.

He wrote "LT pace is a pace at which you could talk but you prefer not to ;)"

At marathon pace, unless you are actually running a marathon and approaching the end, you should be able to have an almost normal conversation.

At LT pace you can talk in half sentences or short sentences but you definitely would be more comfortable not talking.

OP, yes, 8-10 s variation is OK.

Go by Rhodo and Impala's posts.

This is also bad advice. There was a point where I was in sub 5 mile shape but my 5k might have been 18:30. An 18:30 is literally 5:57 pace. So your "rule" means I should have been doing these workouts at my 5k race pace for a longer time???

Seems like an idiotic question.

But on the other thread I made on this subject, I saw that basically no one has difficulty to hit target paces in the afternoon, after running easy in the morning.

While I find it pretty much impossible to hit my threshold pace if I've already run that day, even if it was 4 miles easy (imagine, 4 miles easy, that should be nothing.

What could the reason be? I still don't have enought endurance, I'm not used to run on tired legs (despite running high mileage and doubling everyday)

It puzzles me.

Threshold is not a pace but an effort. I doubt you're having difficulty hitting the effort.
