Race taper - what to do?

I finished my second sprint on Saturday--had a decent race though the run was beyond awful--and three days later I'm wondering what to do for the OLY I have coming up on Sunday.

I've never done an OLY, and quite frankly because of a knee injury I haven't really trained myself up for the distance.  After the sprint I was hoping to get a solid taper in Monday through Friday but I'm undecided right now if training at all this week is a good idea.  Basically, I have pretty bad cramping--still--in my inner quad, that goes from mid-thigh down toward the knee.  It's not an injury of any sort, it's just a badly cramped muscle that despite my best efforts (tons of water and sodium, massage, ice, rest, etc) just won't go away.  I'm pretty sure I can bike without any issue, but I'm also wondering if rest is the simple solution to this problem.

So I put this to the forum: with just today through Saturday to get a few days of training/tapering in, what would you suggest?  I had originally scheduled a bike ride on the OLY course for today, a half hour interval run tomorrow, a 10x100 swim on Thursday, Friday as a rest day then a slow 5 mile bike, 1 mi jog on Saturday.  Any suggestions on how to modify this?  Should I scrap any run/bike training this week and just concentrate on getting the quad back into working shape, go with the original plan and see how it feels or maybe something altogether different?  Keep in mind this is my first OLY...the swim will be absolutely fine, the bike won't be a problem at all, but the run is going to kill me, no question about it. 

Thanks for any and all help, I appreciate it!
