10 w/6x1000. Fail.

Supposed to be at 5k pace. Actual split paces: tempo, 10k, HM, tempo, 10k, 5k. Finally got it on the last one. 

Part of it may be because I was on my usual route rather than the track. So my body thought I was taking it on a tempo run.

But mostly I guess I am still feeling the after-effects of Sunday's race. Kind of beat up.

I sincerely don't know how it can be useful in a marathon training plan to do 6x1000 at 5K pace. Either you fail, which is not very motivating, or you make it but are drained of energy for next day's run. I know Pfitz knows better than me, but it does not make sense IMO.

I would do that workout in 5K training mode, near the end of training, with a RD next day or a very easy run, but not with the kind of mileage you're doing.

Or what I'd do in marathon training is run them at 10K pace. Makes all the difference in the world.
