Scientists have a pretty clear picture of what happens when summer sunlight, high air temperatures and/or humidity increase both skin and core temperatures in runners who increase their mileage training for a fall marathon or cyclists and triathletes preparing for autumn events. They bake. Muscles in motion generate enormous amounts of energy, only about 25 percent of which is used in contractions. The other 75 percent or so becomes body heat. Yet why someone has more difficulty dissipating body heat on one hot afternoon’s run than on another is still mysterious.
The 2018 NBA Champion Golden State Warriors have plenty going for them on the court. But it's the players’ off-the-court moves that really set the team apart from past dynasties. Take point guard Stephen Curry, one of the most adored and spectacularly-skilled basketball players on the planet today. His ball-handling, passing, and three-point shooting abilities are downright otherworldly, routinely leaving spectators in the stands (as well as players on opposing teams) with their jaws dropped. How does he do it?
One thing I love about the Bolder Boulder Citizen’s Race is that the frequent bends and turns in the course offer a perfect opportunity to employ a fun racing tactic I learned from the great Frank Shorter:"In any kind of distance race there is an invisible thread that stretches about 10 meters. If a fellow competitor is running 10 meters or less in front of you, you’ll find that you can usually pull even or spurt past them anytime you choose."
Approached confidently, varying the terrain on which you train actually helps you become more efficient and reduces your chances of injury by breaking up the repetition of the same motions. The more precise coordination required to accelerate down a hill or to sustain a steady rhythm up to the top of a mountain pass when combined with the corresponding changes in cadence and habitual stride patterns serve to alleviate the repetitive-stress (and aches and pains) of running the same pace mile after mile on the flats.
Before the London Marathon in April, Eliud Kipchoge promised a “beautiful race.” He delivered, as he always does. What I love about Eliud (besides his magnanimous smile) is that he clearly understands the importance of trunk training: he uses almost all pelvic rhythm to quicken his leg rate, like revolutions per minute. He runs from the belly, which tapers the muscular effort in his legs and feet. It's something to see.
