During Week 3, I always found the 3 minute runs extremely tiring, especially the second repetition, so I was dreading Week 4.
However, when I did my first Week 4 run yesterday, it was a lot easier than I expected, especially as part of the route is on a pretty steep incline. That must mean that this program is working I definitely would not have been able to managed that much running four weeks ago!
I can't wait until I can get to the stage where I can run continuously for 30 minutes
