Friction Freedom
"Friction Freedom chamois cream was developed by cyclists, for cyclists. Not only is Friction Freedom great for cyclists, but it is also used by horsemen, motocross'rs, runners, rowers, triathletes, and surfers to relieve the pain of friction and chaffing."

Does Proper Hydration Play a Significant Role in Training and Performance in Cooler Environmental Conditions?
By Ronald Mendel, PhD
Here’s what we know…..
Cold exposure has been shown to cause fluid losses on the order of 2-5% of body mass (O’brien et al. 1996). Many reasons have been linked to this dehydration induced by cold exposure including reduced voluntary fluid intake, poor access to water, reduced thirst sensitivity, sweating due to exercise and clothing (O’brien et al. 1996, Ramanathan 1964, Freund and Sawka 1996, Wyant and Caron 1983).
Kenefick et al. (2004) examined whether hypohydration (dehydration) altered thermoregulation and cardiovascular responses to exercise in the cold. We know that these responses are altered in the heat, but it was unclear in the cold. The data demonstrated that moderate intensity exercise while dehydrated did not alter metabolic heat production, skin temperature or heat loss. It also did not increase thermoregulatory or cardiovascular strain. Despite these findings, one thing remains clear. It is imperative to maintain hydration status even in cold environments.
From a practical standpoint, prolonged exercise in the cold can still produce heat at a greater rate than heat is lost. This will obviously lead to heat storage and a subsequent increase in core temperature. This increase in core temperature can, and will, be compounded by dehydration due to any one of the reasons noted earlier.
Ventilation (breathing) increases in the cold. Most people don’t realize how much fluid is lost through ventilation even normally. So when ventilation is increased due to cooler temperatures, the amount of fluid loss just from breathing has the potential to be rather significant.
Reduced voluntary intake is also a major factor that may lead to dehydration of athletes while exercising in the cold. Athletes tend to think less about fluids and proper hydration because they don’t perceive themselves to sweat as much when they train in the cooler environment, and therefore, have a tendency to consume less fluid. This may or may not be true depending on the clothing that is worn. An overall reduced sensitivity to thirst is also a contributory factor in not consuming enough fluids while exercising in colder environments.
Also of significance, and maybe even more important than hydration, is the metabolic response to training in cold temperatures. Cold exposure increases the use of carbohydrates as a fuel. Even during light exercise, muscle glycogen decreases at a faster rate in colder temperatures than warm temperatures. This increases reliance on glycogen reduces the ability to exercise at a higher intensity for extended periods of time because carbohydrates fuel intense exercise. Therefore, ingesting fluids and carbohydrates prior to and during exercise in cooler environmental conditions seem to be quite prudent.

Not just for the track or trail...
After an hour or so in ER and after several tests, it was determined that I was suffering from acute pancreaititis.
I would spend the next seven days in the hospital tied to IV's and pain medication. When I was finally released, and free of the constant blood tests and examinations, I was stoked. I had to continue my low fat diet and stick with soft foods for awhile, but at least I was home.
On day three of being home, my wonderful wife bought me a veggie sandwich. I ate it and I tried to eat it slow, but I ended up destroying it in record time. I felt great, but I failed to increase my water intake to compensate for the solid food. Five hours later, I was back in the hospital. I was dizzy, light headed, my pulse was racing, and my mouth was dry. I didn't know what was going on, but I knew if anything changed in my health, I was supposed to go back to the ER.
Once back at the ER, the doctors quickly determined my problem. Too much solid food with out enough fluids. Back on the IV.
Two (2) liters of fluids later, everything had returned to normal. Heart rate, blood pressure, and O2 were back to healthy levels.
My doctor released me with orders to stay hydrated. Keep the water going and use an electrolyte drink to help get back on the road. I asked him if I could use Motor Tabs instead of the other electrolyte drinks and, after looking at the package of Motor Tabs, said he uses the same product (the doctor is a triathlete and uses Motor Tabs) and said this would be perfect!
I started drinking my Motor Tabs, just one tab a day, on Saturday. It's Monday now and I honestly feel so much better. Motor Tabs helped me stay hydrated which helped my body to recover which means I'll soon be able to return to work and I'll be back on the bike much sooner!
