When your legs feel dead, do you rest up or go for a long slow run?

Depends on your training and age

I wasn't feeling as good as I normally do this last week so I went out for a couple runs at slower than 8 flat pace and ate a bunch of ice cream and junk food...ended up running my 2nd fastest 5k ever today.

Who knows if it works but I must have done something right.

The slow bit is good but you don't want it to be long

When I feel really tired especially in my legs I'll go for my regular run scheduled for the day but I will do it super slow. For me I will do it on the Tmill, I'll start @ 6.1 mph and then increase it by .1 for each mile I run. I did this Thurs, ran 6 statrting @ 9:50 pace and ended the run @ 9:06 pace. My legs flet so much better afterward because I flushed a lot of the crap that was making them feel tired. Try it next time you feel like that and do not worry about the pave being to slow. Good luck.

long run, definitely. It is the one thing I can always count on in training. Everything else seems to change endlessly. But dead legs means go for a long slow run.
