I just wrote an article for active.com on tips for exercising in the heat. Do you have any other tips other than the ones I mentioned. Here is the link:
As mentioned, the link could not be found. Not knowing what your wrote, and having competed and coached in the heat of Arizona, New Mexico and the southeast, the one key consideration is adequate hydration. Frequent consumption of 2-3 ounces of fluid is critical. Also, replenishment of glucose (banana, “power bar” type foods) is especially important in long duration events.
If you get a correction on te link, let us know so we can add any additional comments.
