Hi I have just got back from my week 4 day 2 run and I am really struggling with this week. I have been managing to complete the runs but am finding the 5 minute stints to be really difficult. I have looked forward to week 5 and I am not sure if I will manage it. I may have to repeat week 4. It is a very hot morning so this may have contributed to my struggles. Does it ever get easier?
