I started a 800m challenge at the school I work, so I wanted to get a feel for the tempo required. Pluss it was freesing and windy so I cut down on the speed work. Speed and tempo in the same workout not optimal I guess.

I’m pretty sure that’s the case. I think I remember charlie saying that if you do thw two in one session they sort of dampen the effect of each other…
