It is going to be hot, ridiculously hot.
We’ll head for the shade of the woods, bring water, we’ll run a little slower. When conditions are not ideal, we run to the level of the conditions not to a pace chart.
First 10 X 1 min on 1 min off fartleks (effort should be about 3k/mile effort)
Then
8-10 X 30-40 second hill repeats, full recovery between each (walking and jogging down the hill may be enough, but if you need more rest take it)
Shorter intervals with longer rest hopefully will make the heat somewhat more bearable. If the heat is too much, call it, don’t be a hero.
