Hi everyone!
Carole, I agree w/ Dave. Just work on hitting the times, and as you increase your times and build your endurance, your times will improve. You shouldn't even think about your pace until you can easily run for 1 hour without stopping. Once you can do that, clock your pace for 1 hour, then a couple of days later, drop back to a 25-30 min run and clock your pace again...I bet money it's faster.
Dave, I have been resting since Sunday so I have not been doing anything, but normally I run Sun, Tue, Thurs, have Fri as a total rest day, and I do weight training on Mon, Wed, Sat. I have a set of Bowflex adjustable dumbells at home, and a Bowflex bench, and I can do anything I need w/ that equipment. I do different body parts each day. Monday is Back and Biceps, Wednesday is Shoulders/Triceps, Saturday is Chest/Abs, and I used to do legs on Sunday, but I figure w/ all the running, my legs are already lean and toned so I let the running take care of that.
CW...after consulting my good friend who runs 40-70 miles per week, I am going to rest through the weekend and see how I feel. I think that I actually injured myself in about week 2 or 3, and just kept running anyway, so I have most likely been making it worse for the last 6-7 weeks, and just masking the pain w/ Motrin...hence the reason that I am hurting now. My buddy reminded me though that Motrin contains Ibuprofen which is pretty hard on the liver, so popping 1000mg at a time is probably not too good for me long term. Hopefully I will be able to start the GW28K next week. Worst case is I will just be a week or so behind you.
Never thought I would be sidelined w/ and injury. I guess it's just a reminder that I'm not as young and indestructible as I once was 
Keep up the great work everyone!
