Although my hamstring/glute issue went the wrong direction - which led me to more time on the elliptical and stationary bike - I still should be good to go next Sunday. I'm going to start up a ibuprofen regimine again tomorrow. I expect it will work as well as it did before Philly.
Obviously this is not what I envisioned 6 months ago - I don't want to come limping into Chicago after six weeks of dealing with an injury. But Philly went pretty well - and I've kept up my cardio on the elliptical and bike, but I won't know how things are going to go until I get out there.
On the positive side - the weather should be nice and cool. I'm planning on writing a few more posts this week about Chicago and the marathon. Being injured is no excuse for being boring.
