Yes, I managed the 5 minute runs of week 4. Don't know if anyone else noticed a blip in the podcast? The last few runs are 3min, then 90sec walk then 5 min run....the 90 sec walk between the two runs on my podcast only gave a 60 second walk! I thought it was quick on the 1st 2 sessions, and made sure I checked it on the last session and sure enough, Laura said 90 seconds walk, and the podcast only gave 60 seconds. So, if any of you other week 4 runners are thinking that walk was quick, well it was as it's 30 seconds short of what it should be! Anyway, I managed all of week 4 on the treadmill, now onto week 5 and looking forward to my first session tonight....however, feeling scared about w5r3!!
