Skinny, for a second there you had me worried I'd set too fast zones.
But I checked back, and your tempo will be 6.40, your 10k pace is 6.30-6.35.
It didn't come out too clearly on the other page, so let me re-write it as RW isn't allowing edits at the mo
- EASY 8.05-9.00
- STEADY 7.20-7.50
- MP 7.05-7.10
- HMP 6.45
- TEMPO 6.40
- 10K 6.30-6.35
Before my race yesterday, using my half marathon pb, the time it predicted me was within 1 second of my actual 10mile pb. Therefore, I think the prediction from half to 10m is spot on, whereas it gives times a bit too quick as you go to the shorter stuff.
Therefore, 1:29:08 half pb is 6.48 per mile, and thus your 10mile would be 7seconds quicker for 6.41
A 6.41 10miler would give you 66:50, so sub 67 looks a spot on target to me.
