I have one that I put into practice, today -- pickle juice for cramps (or to ward off imminent cramps).

I'd always heard this worked and I like pickles, but had never tried it. I had 3 disastrous marathons, thanks to cramping issues in my calves.

Today during a humid and hilly century ride I was feeling that familiar tightness that precedes cramps. About 5 miles from the finish we made a quick stop at a convenience store to refill bottles and because one of our riders was having blood sugar issues (we're on a JDRF fundraising team; he was having issues an his blood sugar meter battery died, so he called his mom to rescue him). I decided to buy a pre-packaged pickle in juice to see if it would help my issues.

And it totally did. I was popping Endurolytes like candy and guzzling Powerade like there was no tomorrow...and still feeling the tightness. Within a mile of sucking down that pickle juice (a few oz. worth) my legs had relaxed...it was astounding. NOW I see why ultra runners swear by the stuff!
