There is fantastic track in Chamonix, France, just next to the starting line of the Ultra-Trail du Mont-Blanc (UTMB). It’s a picturesque setting, with the stunning Alps framing the background. For some odd reason, when thousands of athletes descend upon Chamonix every August for the 100-mile UTMB and its companion races, many of them feel the need to do mile repeats and 5K time trials around the pristine, smooth track surface. The last time I checked, there’s not one speck of track surface on any of the trails around Chamonix. The concept of specificity extends beyond the surface under your feet. You can, and should, extend that concept to every aspect of the race. The degree to which you can apply specificity to training makes you better prepared for all the elements on race day, including the intensity, duration, environmental conditions, and whatever other troubles and tribulations you might encounter.
