Hi blayne, sorry for the late reply.
I actually struggled more with week 9- week 10 day 1 felt better for me, probably various factors. I preferred having 3 reps instead of 4 despite being longer runs. Feels like your getting through it quicker! What always works for me is constantly changing my running route too as well as thinking 'I'll just start running and see what happens' just to get me started lol.
Just go for it (if you haven't already), if I can do it not running so regularly then anyone can!
