First run of week 7 done. Been struggling (both, to finish runs, and motivation-wise) since week 5. That being said, I still keep managing the runs and I'm, pretty much, completely injury free, so far (although I did put a knee support on, for one run when my knee was a bit iffy). I think, after a while, it's far more of a mental challenge than a physical one (especially, as my depression has been quite bad lately). My legs start feeling like lead, only 3 or so minutes in. I feel my head and body feeling really hot, within 5 minutes. Then it's a gruelling 20 plus minutes to keep going after that.
Keep going, everyone. Rest and recover if you need some extra time away. But don't give up. One step at a time.
