Welcome to another instalment of Pelotan Performance Insights! In this edition, to mark the first day in the high mountains at the Tour de France, we're focusing on the crucial relationship between altitude and UV exposure, especially relevant for cyclists tackling mountainous terrain.
The Hidden Risk of High Altitude
Did you know that as you ascend in altitude, UV radiation increases significantly? Research shows that UV levels can rise by 10-12% for every 1,000 meters (3,280 feet) of elevation gain. This heightened exposure can have serious implications for athletes who spend extended periods at high altitudes, such as during mountain stages of professional cycling races like the Tour de France.
Supporting Data
-
Study by the World Health Organization (WHO): The WHO reports that UV radiation exposure increases by approximately 10-12% for every 1,000 meters of altitude. This means that at 2,000 meters (6,561 feet), you could be facing up to 24% more UV radiation compared to sea level.
-
Tour de Suisse Study: Observations during the Tour de Suisse have shown that cyclists at high altitudes experienced increased UV exposure, with UV intensity measurements taken at elevations exceeding 1,500 meters (4,921 feet) indicating significantly higher levels compared to those at lower altitudes. The study highlights the necessity for effective sun protection during high-altitude stages - especially when it's day 4 of a 3 week race...
-
Tour de France Observations: During the Tour de France, cyclists ascend to elevations even higher, such as today and the famous climbs of Col du Galibier (2,642m). These stages expose riders to significantly higher UV radiation levels, necessitating robust sun protection.
Why It Matters
Increased UV exposure at high altitudes can lead to quicker sunburn, accelerated skin damage (meaning more recovery needed), and a higher risk of skin cancer. For cyclists, this is compounded by the length of time of these huge climbs and the reflective surfaces like roads and snow that further amplify UV exposure.
As you prepare for your next high-altitude ride, remember the heightened UV risk and make Pelotan your trusted companion. Stay protected, stay strong, and conquer every summit with confidence.
Stay safe and keep pushing your limits!
