PR in the mile and a little slow on the 8:00. I went out on the mile trying to break 5:00 but just fell back. I’m curious tho, if my 5k Pr is 18:44 and 800 PR is 2:22 then what does a logical mile time sound like? I think I’ll definitely break 5:00 soon but I need a lot more work first.

I’ve heard tempo/threshold long runs are bad. Is this accurate? Because I tapped into threshold today during my 12k long run.

Why am I having such a huge spike in heart rate at 10-11 minutes into my 5k. It’s happened twice now but the effort between before it spikes and after feels the same. Is it that I’m hitting the lactate curve? Or is there another reason?

Is there any way to keep building/maintaining aerobic base while sick?

Finally felt great and training is paying off. Probably could have gone a little faster at the end but I knew I was going sub 20. Also I didn’t mean to lap it at .15.
