I agree with thenewgreen that the run works to boost almost any state. Of course, as it dehydrates, it might make the post-run party better (faster alcohol absorption) and the recovery worse (same reason). But that's just one more cause to hydrate aggressively. Or simply cleverly, using tricks of science such as "electrolytes." Before distance running, I had no personal sensory experience to verify their magic, but now, I am quite the passionate advocate. My favorites are the naturally occurring ones, such as watermelon juice and coconut water, although I understand their ratios of sodium to other minerals may not be perfectly ideal. I take it you had something of a hangover, just not much?

Now that I'm re-reading, I'm figuring out you meant to preempt the hangover's blooming into something much worse, not as a pre-festivity measure. And yes, provided adequate hydration/nutrition go along with it, I think the run is an excellent way to nip an accelerating hangover in the bud.

Looks like a fun route. I think I see some park space on the west end of it, though I don't know how much of your course actually boasted tree-shade. I'm really reliant on that in this weather, which can pose a challenge. Cities (the American ones I've been to, that is) are just not arranged for the health and comfort of long distance pedestrians/runners. I wonder which city is the runner's paradise? Perhaps it's just the place closest to the longest system of trails. Any nominees?
