A runner loses heat via sweating. This sweat evaporates on the skin which dissipates heat by convection, assuming that humidity is low enough. Heat stroke will occur when the bodies thermoregulation is overwhelmed.
Overwhelming the body (in simplistic terms) may come from excessive environmental heat (running in a hot climate), running too fast or too hard, being dehydrated, a lack of free flowing air that will help cool the body or a lack of water to splash on the body to cool down.

Extreme by name, extreme by nature, the names of Red Bull and Kilian Jornet are almost a match made in heaven, equally renowned for pursuing the extreme.
Red Bull pursue the extreme in everything that they do… skateboarding with Ryan Scheckler, Ryan Doyle with Parkour, Travis Rice on a snowboard and so on, irrespective of the athlete or the sport, Red Bull push the boundaries.

It seems appropriate that the third edition of the Red Bull Elements, located at Talloires on the shores of Lake Annecy should once again have the presence of Salomon sponsored athlete, Kilian Jornet.
It’s not the first time for Kilian to experience a Red Bull Extreme event. He is a two-time winner after participating in Red Bull Elements with his Font Romeu Team. However, he can’t win single-handed. Red Bull Elements is a one-day multi-sport adventure race. Competing as a team relay, the race celebrates three elements – air, earth and water – through four sports,
Rowers, runners, paragliders and mountain bikers join forces to compete in the same outdoor world! The race is a pure concentration of endurance sports. Uniting all those involved. It creates a dramatic and extreme event.
On Saturday, September 14th, 216 athletes grouped together in 56 teams will start an adventure with rowers covering 14km in Talloires bay.
Handing over to the trail runners, Kilian Jornet and his adversaries (such as Salomon teammate, Michel Lanne) will then climb eleven kilometers covering a vertical gain of 1914m with only 25m of negative gain!
At the summit, paragliders take over and they descend to a rendezvous with the final discipline; mountain biking. A final breakneck descent to Talloires village culminates the event.
Of course, this event is not about Kilian Jornet. On the contrary, he is very much just one cog in a very important four-person team. However, my emphasis and sport is running and in particular mountain and trail running, so, the question remains; can Kilian improve on his extraordinary performance from 2012? Last year, Kilian Jornet completed the 11 km of ascent in less than 1h: 20m. For sure, Michel Lanne will push him all the way to the summit. I just wish I was in Annecy to watch the action unfold… it really looks quite an incredible event!

“Drink as much as you can, even before you feel thirsty.” That’s been the mantra to athletes and coaches for the past three decades, and bottled water and sports drinks have flourished into billion-dollar industries in the same short time. The problem is that an overhydrated athlete is at a performance disadvantage and at risk of exercise-associated hyponatremia (EAH)–a potentially fatal condition.
Dr. Tim Noakes takes you inside the science of athlete hydration for a fascinating look at the human body’s need for water and how it uses the liquids it ingests. He also chronicles the shaky research that reported findings contrary to results in nearly all of Noakes’ extensive and since-confirmed studies.
In Waterlogged, Noakes sets the record straight, exposing the myths surrounding dehydration and presenting up-to-date hydration guidelines for endurance sport and prolonged training activities. Enough with oversold sports drinks and obsessing over water consumption before, during, and after every workout, he says. Time for the facts—and the prevention of any more needless fatalities.
