Been lurking for a while and have enjoyed reading a lot of useful posts.
Just completed week 6 but it really felt like a struggle. 25 minutes seemed ages and I'm not enjoying it at all like the earlier weeks. Almost stopped after 5 minutes (felt mild knee and back pain) but after doing the "am I really hurting so much I need to stop" check, I carried on.
I dropped my speed this run back to two 12 minute miles so I'm sure I'm not running too fast (my pace was an 11 minute mile for W6R2)
Anyone else hit the "I'm not enjoying this right now" around week 6 / 7? I didn't enjoy the 20 minute week 5 run either (was in Spain for that one!).
