I'd skip the beer...definitely skip the multiple beers. Hydration is what you need as well as food. I will often sip on some electrolytes throughout the rest of day 1.

Compression tights are amazing. I have some not horribly tight ones that I will sleep in between races. Sometimes inverting your legs against a wall can help.

I am a fan of heat and massage (followed by menthol/analgesics and/or compression) over ice for muscle recover, but ice on joints if needed.

How regularly do you do back to back hard training days? When I have not been able to do those, then my post-race recovery time greatly increases for 2 race day weekends.

Stay off your feet (I am bad about this)! Don't forget the saying, "Don't stand when you can sit. Don't sit when you can lie down."
