It's scaring me too but the 20 minutes on day 3 is even worse! We can do it! I start Week 5/Day 1 tomorrow so I'm just behind you.

I just finished Week 5 Day 3. I had really freaked myself out about the run and when I first started running it seemed like I wasn't even gonna make 5 minutes, but then I just started watching my form and breathing and telling myself I wasn't gonna be a quitter. Ended up running 24 minutes instead of 20 because I had decided to do distance rather than time.

I was surprised at how well the 20 min run went. W6 D2&D3 are intervals again. That was harder. So I talked to a fitness instructor I know who is also a runner and she said intervals are without a doubt harder and the beginning of the run is always the hardest. I felt skeptical about that. In my mind it made sense that you start off with energy and as you tire it gets harder. But I think you have to run for a very long distance before that is the case. Sure enough, the 25 min run on W6 D3 wasnt bad once I hit my stride. Same with weeks 8&9 (28 & 30 minute runs.) I noticed on these long runs that my fitness coach was right. The 1st 6-8 mins are the killer. By the time I hit 10 mins my body gets comfortable and acclimated to running. Now I have done 45 mins of straight running. None of it is worse than the feeling that hits me around 6 mins in! So hang in there, the best part comes later.
