I posted this in Basic Training, but I thought I might get more responses here since it is injury related.

My Wife and I began training for the Chicago Marathon back in February. We built a good base of 20 mpw for several months before beginning the 17-week beginner marathon training schedule from marathon.com (?) Everything was going well, until 2 weeks ago. We were on our first 20 mile run when my wife started having knee problems. I knew it was an IT band issue since I've had ITB problems in the past. She has taken about 10 days of rest. She started back slowly last week after having applied ice religiously and frequent stretching and use of the foam roller. These strategies worked for my ITB problems. Anyway, last week she successfully ran a couple of 4 milers with no pain. My question is....now what? We have 6 weeks to go. Should she jump right back into the training? Our schedule for the remaining long runs is 21,14,8,22,12,10, Marathon. Obviously she wont do the 21 miler this weekend, but should she try the 8 miler? Then what? Any suggestions for her?
