5 K or Marathon: Which is Harder?

5K

Which is harder, to run 3.1 miles or 26.2?  They are equally hard for the runner who runs right.  The agony and the ecstasy at the end of a race run right is the same whether induced by 42.2 km of LSD or 5 km of POT.  Above, I am approaching the final stretch of a 5 K trail race (2nd annual CAAFA 5K Race Against Violence, Prospector Park, Apache Junction, Arizona).  The date is wrong: should be 3/21/2010.  I finished in 45th place in a mixed field of 113, and 28th among 44 men.  Time: 33:38.8 for a pace of 10:49.8.  That's nothing to crow about, but then I'm 60 as is the gal right behind me.  Twenty years ago I could cover this distance at a 7:45 min/mile pace.  There were five 60+ males and I finished first among them.  Not a strong field!  But a beautiful cool crisp morning and a great course and a great run.  I could have pushed harder!  Could have and should have.

LSD: long slow distance.  POT: plenty of tempo.  Both terms borrowed from Joe Henderson.

How To Roast Oneself in Five Different Ways

IMG_0199 The infernal hike of 28 August 2005  began at 5:20 AM at first light, that phase of dawn at which one can just make out the trail and its hazards. Sunrise was about forty minutes off. If one hopes to survive a desert hike in August, especially in environs as rugged and unforgiving as the Superstition Wilderness, one does well to start at first light and be finished by high noon. I once finished such a hike around two or three in the afternoon with the distinct impression that I had pushed the envelope about as far as possible.

It is a curious sensation to feel oneself being slowly roasted in five different ways.

There is first of all the air temperature. Today's for example was 112 degrees Fahrenheit at its high. At any temperature above 90 the human body starts to absorb heat through the skin.

Then there is conduction. One gains heat by contact with the ground, rocks, ledges, anything one touches while hiking or climbing if the object is hotter than 90 degrees.

In third place comes convection. Hot air blows against the skin and imparts heat to the body. Even a slight breeze at 112 degrees has quite an effect.

Fourth, there is solar radiation. Once up, Old Sol beats down unmercifully, which is why I wear a long-sleeved white shirt and a broad-brimmed hat. My legs remain exposed, though, since hiking in long pants is unbearably confining.

Finally, there is metabolism. The internal organs and the muscles at work generate body heat.

I finished at 11:10 with the day's high of 112 degrees Fahrnheit fast approaching. I was well-roasted and dehydrated, but very satisfied with the five hours and fifty minutes I spent hiking over washed-out, overgrown, ankle-busting trails.

I concur with Colin Fletcher: Hiking is "a delectable madness, very good for sanity, and I recommend it with passion." (The Complete Walker III, p. 3)
