Week 4 run 3. I started off feeling a bit sick, so might have been because lunch hadn't been long enough ago? Then got to the first 5 min run and at about half way Laura stopped! I walked a bit then ran until the 4 min mark and couldn't complete 5 mins. Got through the next 3 min, but the last 5 min stumped me half way again. I walked the rest. Then I started the pod cast again and did another 5 min walk and tried to run the 3 min. My lower back pain is back which stopped at week 2. Very disappointed and feeling like I'm losing not gaining (sadly not weight!) anyone else had a bad week 4?
