Yes, 10x400m or 5x800m is rather a lot for a first go. I have already built up to 7x400m reps over the last couple of months so 5x800m was less of a leap. I haven't run yet today but not feeling like yesterday's session has sapped me particularly. If I toddle out for my 3 miles and struggle I'll perhaps wind my neck in next week.

FWIW my 400m intervals were 1m41s average... so 6.44mm pace I think. I can't remember off the top of my head what the Joker recommended pace is for me.

And there is no way on this earth I am plummeting into the dark despair of heart rate training ever, ever again.

Just saying.

Lolz.

I'll go by perceived effort and how I feel afterwards, plus a sensible seeming pace guide... which it seems is not the project Joker pace guide!!

Having never done it, what was so bad about HR training?

Intervals as originally designed involved stressing your HR to 180 then having a break of up to 90 secs. Also interval referred to the recovery as that was the important bit.

Obviously flaws in the 180 protocol but at the time for the elite individuals it was used for, it would have worked well.

Extracts from Daniels Running Formula. Main section on I and below the line on R.

Note that Daniel's says he decided to make his own definition so this isn't universal and doesn't makes sense to impose on other training methods. Fine for those talking about Daniel's training but not as a generic things.

I'm a bit confused about what pace I should be running intervals at.

I always thought it was "as fast as possible while making the last interval as fast as the first". I did that today and felt awesome about it. Even did the last interval a few seconds faster than the first so wasn't flagging at all.

But I've just put my recent 5k into Project Joker and it gives me a pace for intervals much slower than that.

For reference.

5K time - 24m10s.
Recommended time for 80...
