I hate tradmill running with a passion lol.
Yeah the 1km reps are the one along with hill reps.
That's what I did last time.
It's very a very hot summer and job circumstances to stay at the consistent level I was for the marathon earlier in the year. I've got a full set of the main distance new PBs this year. 10k isn't a problem most days but even today I went out deciding just over 5 mile was enough between recovery cruise and steady.
