Salt, Don't leave home without it!

The one item you should not go to Kiehl's Badwater Ultramarathon without is salt tablets.
The runners need it and your crew better be taking it too.
Since I fell into ultrarunning and the ultrarunners in this area, I have used almost exclusively Succed S-caps (just so you know there is no sponsorship or remuneration for this plug).
I do not work on the scientific side of things and know only the combination of items in the caps, reportedly the highest doses of what you need that you can get in a salt cap, has always seemly worked for me.
The race can seriously deplete your body's salt content from not only the strain of running it but also the heat induced sweat.
During the race I weigh just under 200 pounds and was talking one cap every 20-minutes during the heat of the day.
After the sun was down I was taking one every hour or so. Last year the temperature really dropped to about 68 degrees just before the sun came up. After the heat of earlier in the day, it seemed really chilly.
