OK, I successfully completed the second run of week 4 tonight. It was brutal, but not as bad as the first run of week 4. During the first run, the first 5 minute run segment seemed like it took forever and when Laura said that I was half-way through, I literally said out loud that "you have got to be kidding me." The second 5 minutes of the first run of week 4 was more of a fast walk than a light jog, but I finished. I was not looking forward to W4R2, but I ran it tonight. I felt like I still had a little gas in the tank both times that Laura told me that I was half-way through both 5 minute runs. I finished both but, again, it wasn't pretty. This has been the most difficult week so far for me. I guess that's to be expected since the weeks keep getting harder and involve more running than walking. In the end, though, I've begun wondering if I've hit the wall and maxed-out on my running ability. It is now very hard for me to see how I can run for much longer than the 3 and 5 minute runs for this week. I've read a lot about the difficulty of week 5 and wonder if I'll get through that week, let alone make it through week 9.
