I've just completed week four. I was worried about it because I got less sleep than usual last night (and ate too much chocolate) but it was a really good run! I only looked to the end of the run during the last minute of the final five minutes! The only thing I know about week five though is that it includes twenty minutes, and I'm terrified!
What earphones do you all use? I have some buds but they keep jumping out of my ears. I can't spend too much, but suggestions would be fantastic- thanks in advance!
