Cycling A 9.2 KM Uphill Time Trail

Larger cycling events that take place over the course of several days sometimes include one or more climbing stages. What’s it take to get over the top? A study published in the International Journal of Sports Physiology and Performance analyzes the physiological demands of competing in a 9.2 KM race up a 7.1% slope.
 
Fourteen elite road cyclists completed the race. The first, second, sixth and final kilometers were the most physically challenging, and the race was performed at an average 90% of maximum heart rate and 90% of maximal oxygen capacity using 70% of maximum power output.
