Ready to start tapering

Last Sunday was an epic 12 mile run, the farthest I've ever run in one outing.  It will be the longest training run I have, since this weekend is the Marine Corps Marathon.  I am not running the MCM itself, but the MCM10k.  I am not sure if I aim to break my current PR, since doing so may adversely affect my Richmond Half Marathon performance, but I may just go for it.  The weather looks to be nice.  I'll be at the expo this Saturday morning.
