I represent what is left of a vanishing race, and that is the pedestrian.... That I am still able to be here, I owe to a keen eye and a nimble pair of legs. But I know they'll get me someday. ~Will Rogers
Rarely if ever do my wife and I vehemently disagree. And even more rare is the heated argument between the two of us. The only time a casual observer might event consider the slightest bit of discord between us is during those times when pedestrian and motor vehicle meet in the public thoroughfare.
The average person would think a running enthusiast and coach would take the side of the walker ambling from point A to point B through the center of a city street.
Absolutely not. I marvel at the foolishness of people who disregard common sense and common courtesy. A marked and signal-controlled crosswalk, not 20 yards farther down the street at the intersection, has been placed there by traffic engineers with compassion and vision. It drives me even more to fury when the same pedestrians cross during the rush hours, or at twilight while wearing subdued outerwear.
I'm not going to go out of my way to strike you, foolish pedestrian, nor will I blow my horn in an effort to startle you out of your reverie. But please don't expect me to be exceedingly kind, either.
What caused Suzanne and I to truly exchange harsh words after a Sunday morning run and brunch at the beach, however, was a family crossing smack dab in the middle of the county highway. With heavy early-afternoon beach trafic traveling both directions. With a baby stroller. I rolled up upon the gentleman with the stroller, but I was no closer to him than the large, honking van rolling up upon his back side.
Suzanne and I were both angry; she at my apparent lack of compassion, me at the gentleman's willful endangerment of his child. I explained that legally, ethically and morally the guy was in the wrong; I would not willingly go out of my way to inflict harm, but in the unlikely event (with perfect weather and visibility, this would be highly unlikely) of a pedestrian strike the worst I would most likely incur is an overwhelming sense of emotional guilt.
"What if it were you and the grandchildren?"
"There's no way I would ever - ever - walk the kids across the street without being in a croswalk. Period."
Normally, I would have not written or discussed this particular topic. But I left home earlier than usual this morning, only to find I would need to take a detour to work. An hour later I read the report of a runner struck and killed by an 18-wheel semi-truck. As always, the details were very limited. The road where the accident occurred is not known for being well-lit; I've driven it at 5:30 in the morning in months past.
Perhaps the runner was not paying attention. Perhaps the trucker wasn't looking out for the other guy, didn't expect anyone to be out for their jog at 5:30 a.m. It's a sad state for all parties. A ton of internal combustion engine and related parts, traveling 40 miles per hour (64 feet/second) has force (128,000 foot-pounds) which far outweighs a 170-pound man traveling 7 miles an hour (11.2 feet/second, 1904 foot-pounds). Even if the pedestrian was in the right, and did all the right things, and was entitled to the right of way, when it comes to close encounters of the vehicular kind, the vehicle always wins.
It's easy to start looking at potential causes, like music player use, lack of lights or reflective clothing, and a lack of situational awareness, just to name a few which easily come to mind. Did the runner decide to take a sudden turn across the street without taking a look behind him, or try to cross an intersection where the "big red hand of death" was displayed? It's difficult to say.
Have I done a lot of things while running which would fall under the realm of self-endangerment; jaywalked, or ran across a street without using the crosswalk? Yes. In the overwhelming majority of cases the nearest vehicle hasn't necessarily been all that near.
I hope that Will Rogers was wrong; that we're not all going to be eventually the victim of a motor vehicle encounter. A keen eye and a nimble pair of legs can only get us so far. Make certain to do the things which will allow you to see and be seen, hear and be heard on the roads. Because if it's all left up to chance, we all know the numbers are not in the runner's favor.

The Courage to Change, The Wisdom to Know
I looked at the runner's watch face, moments after he finished his marathon. He made his goal of under three hours. But to me something felt very wrong.
Late-December clouds, drizzle, and mist might have affected the ability of his Garmin 310XT (the same model I use to measure, train and race) to communicate clearly with the constellation of satellites; it's happened in the past.
Chuck depended on the 310XT for feedback and pace guidance because he was running solo, without benefit of escort vehicle or bicycle on which to gauge his effort. He told me he tried to do the mathematics throughout the run in order to figure out whether he'd make his goal of seven sub-three-hour marathons in seven days. I could see he was not confident of repeating the feat over the next six days, not without accurate feedback outside of his own physiological data.
I drove home and began to walk through the interrogation points I normally give to a GPS user after a race on a course I've measured:
Was he at the exact start line when the horn went off? Yes.
Did he run the shortest possible distance for the entire run? Outside of six-to-eight stops at the outside edge of the track for fluids, he "bloodhounded" the inside lane line.
Did he stop his unit at the exact finish? Most likely; at the worst he stopped it no more than ten meters past the finish mark.
The issue wasn't that his GPS unit registered a distance that was longer than the standard marathon of 26.21876 miles, or 42.195 kilometers. I knew that was going to happen. It was that the GPS unit registered a distance that was much longer than the standard marathon.
An error rate that approaches five percent definitely exceeds my comfort zone. At that point all I could do is start interrogating myself. I've made a mistake, but WHERE?
Maybe on the mathematical calculations? I've been caught with bad calculations in the past, which can cost a day to two days' worth of work, depending on the race distance. I used to use a hand calculator and word processing document in the past to complete my measurement paperwork but quickly learned the joy of Excel spreadsheets. Once you develop a good spreadsheet formula the paperwork turns into "plug and play."
Also, I've had the pleasure of a second measurer in the past two months, as well as the course certifier, looking at my calculations.
The only thing left was to take a look at my calibration. When I first planned the job I was going to do it in kilometers rather than miles; the track was a 400-meter track, so 42.195 was (so I thought!) going to be more simple than doing feet and miles.
Boy, was I wrong.
Back home, I chewed hard on the data, even going out to take a look at my calibration course. It took only an hour of walking up and down the way for me to realize how badly I screwed up.
I punched up the correct data, went back to speak with the race director, and told her I owed Chuck an apology. She understood it was an integrity issue; it took courage to come out and admit the mistake and to fix it as quickly and efficiently as possible. And I guess she was right. I could have let ego, arrogance and even fear force me to keep my mouth shut.
Small-scale misjudgments - whether as a measurer, a coach, or as a runner - may not drastically affect short-distance races, but can be disastrous when it comes to races like the marathon. Think very carefully about all of the training details, because it's the small one that's most likely going to be the most costly.

The Dog - Best Friend, Best Training Partner
My workday routine - once I get into the office - includes two activities which my co-workers and supervisor have seen fit not to infringe upon or drastically modify. First of all, I make certain the coffee is brewed - since my supervisor and several co-workers also drink coffee that's probably the reason I'm not hindered.
The second habit includes reading my favorite comic strips. One strip I enjoy a great deal is "Frazz," drawn by Jef Mallett. The main character, Edwin "Frazz" Frazier, looks like a grown-up version of "Calvin" from Bill Watterston's "Calvin and Hobbes" strip. Frazz loves a teacher, works at a school, runs, bicycles, swims, writes songs... It's a fairly neat parallel of (my) life and Mallet's art.
Not long after I started to follow the strip, Mallet had a week of strips which involved Frazz's girlfriend's dog, "Mario," a rescue greyhound. (And to think the comic strip couldn't get any better...) The most memorable conversation that week had to do with the speed of greyhounds versus human beings. A youngster from the school asked if humans were faster than greyhounds. Frazz replies greyhounds are faster than humans, but humans can run a marathon faster than a greyhound. The child says, "so greyhounds are also smarter than humans." "One would consider the baggie a clue," laments Frazz.
I've occasionally laud my greyhound, Rubin, in blog posts for teaching me the benefits of rest and habit. But, as time has progressed, I cannot help but consider the dog - in the vast majority of cases - to be not only man's best friend, but potentially, man's best training partner.
Several coaches have rhapsodized about training "accountability groups" containing at least three members. The natural reason for having three persons in a training group, naturally, is so the individual athlete need never train alone, except for those rare occasions. Think about it - the odds of having one training partner fall ill, or their family member fall ill, or be on travel, sudden change of work schedule, and so forth - is usually pretty good. But, the chances of having EVERY other training partner in the group suffer from such obstacles grows more unlikely. There is at least one day a week where I feel a little beat up, or I need to be in at work a little more early, etc. So I might try to talk myself out of 25-and-50 workout opportunities a year, which means a one-in-seven or a two-in-seven chance of leaving a partner in a lurch. Then, what are the chances of both other people ill, beat-up, constrained? It's probably right around two-in-one-hundred.
You statisticians or mathematicians out there, please feel free to jump in.
Dogs, on the other hand, don't HAVE to worry about work. To Rubin, every day is Saturday. He's ALWAYS up for a walk, even if the weather is stormy. He might not want to go outside (to do his business) in the pouring rain, but he'll go if I pull on my rain gear.
So, if you've got a dog who likes to run and a route which is amenable to running together, the odds are very high you've got a willing training partner.
Not every breed, however, is built to deal with long-distance running. My mother's German Shorthaired Pointer, Bogie, taught me this lesson almost two decades ago. I had driven down to her home in Jupiter Farms, FL, for a visit. One afternoon, I told her I was going out for a run. She suggested taking Bogie along as company, not suspecting:
First, I didn't know the neighborhood as well as we initially thought.
Second, how far I was capable of running before realizing point number one, and...
Third, how lost I could get myself because of points number one and number two.
Some 90 minutes and nine miles later (as I learned while driving the next day) Bogie and I returned home to a very worried mother-slash-"dog mama." Bogie immediately shoved his face into a bowl of cool water, I grabbed a very large glass of iced tea. He lay down on his bedding in the corner of the living room; I put my legs up in the recliner while enduring the maternal inquisition. The next day, the question, 'Bogie? Want to go for a walk?' was met by a tucked-tail slink out of the kitchen back to the living room.
Greyhounds, I learned, are pretty well good to go where walks and warm/cool-down efforts are concerned. Otherwise they prefer to play the "I'm retired" card for distances longer than a quarter-mile. There's also a terrier or two I've encountered who, if you could control their lateral direction, would probably keep most distance runners on their toes for an extended period of time. I've met herding and working breeds who absolutely love to run and seem to go forever. My friend, Charley, has a couple of Australian Shepherd-types who think nothing in life is greater than to go out running on trail with the local hash kennel. The only problem, naturally, is once the run is over...especially this particular kennel. It's not a proper trail without a water crossing. "The wet dog is the lovingest," was the final line of a poem by Ogden Nash.
Truer words were never inscribed on paper.
When it comes to race day, however, that's where the lines are not only drawn, but the ugliest darned fault lines develop. The race director, especially for a Road Runners Club of America-affiliated club, is constrained by the insurance guidelines which keep Fido from pawing the starting line next to their owner. Then, you have the "keep your dog leashed" crowd, the "my dog is well-behaved" crowd, and the "how dare you risk hurting your dog by making them run in this heat" crowd. Nobody wins; everybody goes home grumpy.
Last spring, a young lady asked if her dog could participate in one of the area's major run events. She said the dog had been her training partner to that point in time, and she figured it would be fun for them both to participate in her first race. I knew the RRCA insurance constraints and the risks which could happen in the pack. However, being "only" a guy who knew a few things about a few things, I suggested she contact the race director so she could get the (bad) news from him directly. I didn't hear any follow-up, but she did thank me for my gracious response.
While not every runner appreciates the presence of a canine on their morning (or afternoon) run, it can be said that nearly every canine appreciates the chance to be in the presence of a runner. And having that always-joyful, never-complaining, almost-always-available running partner can even help us get that first step out the door on the days when we really don't feel like it.

Sunrise, Sunset?
For those few readers old enough to have seen Zero Mostel as the milkman Tevye in "Fiddler on the Roof," this doesn't have anything to do with how we age. Not unless you want it to.
Until about a year ago, I trained twice a day in the three disciplines of triathlon. I would get up before the (butt-) crack of dawn two-to-three times a week and engage in what I jokingly called "creative drowning," something which might have appeared to be (if the light was right and you squinted just so) masters' swimming sessions.
On the days when I wasn't being thrashed by some 80-year-old little old lady (who just so happened to be a national age-group champion) I'd either be on the elliptical trainer or in a spinning class. However, after a disastrous day in Panama City Beach which included an (expensive) emergency room visit, and a less-than-happy day at NOLA 70.3 five months later, I figured it was time to scale back and focus on being mediocre in one sport.
Until three weeks ago, however, I was happy to limit the sessions to an hour in the afternoon, once I arrived home from work. 'Why,' I asked myself, 'should I infringe upon my sleep for something which is only going to make me be more humid once I get into my (semi-)air-conditioned office?' I like sweat, but not so much when I'm sitting in front of my computer. There are only so many excuses you can provide before people start to think you're getting in touch with your inner "Pig-Pen."
Amazing what Mother Nature - and her 90-to-100-degree afternoons - will do to gain a guy's attention. The drive to my office in the morning illustrated a simple mathematics problem and got me to thinking: 75 degrees is still less than 100 degrees.
Like shoe brands, short lengths and training plans, the persons who love running first thing in the morning are not wrong in their decision, only a little different in their preference. To ask some of my close friends why they run in the morning rather than the evening, many consider it to be one "check in the box" out of the way on the seemingly-endless "to-do" list. Some also consider the morning run a (brief) respite from the demands of child-rearing, especially the ones with children engaged in organized sport/activity. Morning runners also figured if they didn't get the run in the morning something during the day or afternoon would infringe upon that time. My southern-tier-dwelling friends also laud more reasonable conditions early in the day.
As much as those particular qualities sounded enticing (save for the non-affect from child-rearing, since I'm only" a grandfather!) I've never been able to put together enough time in the morning to run as long as I preferred. I've always felt rushed to get back to the house by a particular time in order to cool-off, shower, and have a cup of coffee. Sleep, to me, is a guilty pleasure. I only can get so much because of my dog gets up an hour later than I would need to.
Besides, I have my half of the year when I feel rushed to get my run over with...before it's too late. Early sunsets of winter and those countless social occasions between October and February regularly place the kibosh on the evening-loving runners. I love the evening runs because I've usually built up a fairly good head of steam over something which happened at work. Yes, anger is a lousy fuel source, but it's like lighter fluid; only there to get the charcoal glowing. I would much rather stay up a little later in the evening after a run or workout in order to socialize (or relax) than track sweat through the kitchen as I'm grabbing for a slice of toast and coffee.
Sunsets and sunrises are both things of beauty to see on a run, and I've had the opportunity to experience them both with friends. And perhaps it's all in the mind of the individual runner what they prefer. Right now I'm an evening runner. But there are the occasional mornings when I love to prove myself wrong.
