Hi /r/running 

So, I have been training for the Twin Cities Marathon on October 7th.  This will be my first marathon.  I was training with my best friend, John, who tragically [died on July 13 in an auto accident]  The coroner determined it was myocarditis.

He loved running so much. I have continued my training and have made it my mission to run in his honor. Friends and family have been supporting me and are looking forward to me crossing the finish line for John.

Last Thursday the pain came.  Right knee, lateral knee pain.  I have had this injury before in the left knee and the recovery time was about 4 weeks, then slowly back to running.  I do not have this luxury this time around, as the marathon is only 2.5 weeks away.  I know "there will be other races," and I should get healthy.  I know the right thing to do physically. **But, I have to do this; for him and for me.**

I tried to get back out there yesterday and the pain was back after 1 mile.  99% sure this is ITBS as I have had it before.  I have been doing RICE, foam rolling, stretching and strengthening.

So here's what I need:

* How can I get that knee healthy enough to finish the race?
* How can I keep my cardio at the same level over the next 2.5 weeks?

I was pacing at about 9 min/mile, even on long runs, and my goal was to finish under four. I know I am physically ready other than this knee pain.  My goal now is just to finish. *I need to. *

Any advice would be appreciated. **I need this, for him and for me.
