A run without purpose

Today's run (street): 2.25 miles

Runner' World has a story in the August issue that suggests that you have a purpose for every running workout. Examples include building endurance, getting faster and simulating race conditions. This morning the purpose of my run was simply continuity.

It's been a taxing week in the office and I count on my daily run to bring balance to life's pressures and stress. Some mornings I get up and run hard, usually when I'm training for a race. Other times I'm happy to complete my route after averaging a mid-9:00 pace. In both those cases I usually feel like I've contributed to my fitness.

Today's run was more obligatory than tactical. I started out slow, almost as a concession to my begrudging agreement to run. I reached my first mile two minutes later than I normally do and that prompted me to step up the pace. As much as I'm told to run without a watch, seeing my performance playing out on the digital display can motivate me to work harder.

My increased focus on speed allowed me to make up for that first mile pace and I completed the last third of a shortened course at 10K race pace. In the end I was glad to have run and satisfied with my performance recovery. Still, I'm hoping for a more purposeful attitude when I go out for my next run.

Runners: know thy enemy!

Today's run: 2.6 miles

Hoping to keep my cool

Like most runners, my performance degrades with a rise in temperature. Adding humidity makes it worse and it all makes sense scientifically. If your body needs to cool itself, it will deplete your body's fluid level through sweat. This leads to a loss in plasma volume and a reduction in oxygen to muscles because blood low is being pushed to the surface of the skin. Humidity prevents efficient evaporation of sweat that dissipates heat and helps regulate body temperature.

It seems like every running magazine I read has an article or two about running in the heat. They all say basically the same thing -- that proper hydration (including electrolyte balance) is key. They are also pretty clear that running in extreme heat can drive your body temperature up to dangerous levels. At that point it goes from bad to worse.

I'm thinking about this because I'm two weekends away from the Dirty Sock 10K trail run. It's a great race that goes through the woods and around a lake. It's always held the third weekend in August and the two times I've run it conditions ranged from high heat and humidity to high heat, humidity and rain. Last year I drank 24 ounces of water after I finished and still felt depleted. It wasn't until my daughter brought over an electrolyte drink that I finally felt restored and balanced.

This morning's run did not feel humid (though it was) and I appreciated the temperatures that were still in the 70's. I had a decent run and by the time I came home I was drenched with sweat but I didn't feel overheated. I'm looking for a singlet to wear on race day. Despite the "wife-beater" look that I've always avoided, that may be a good tool for keeping my body temperature down. One thing I'm counting on is that Dirty Sock will fall on a hot and humid day.

Puzzling find beneath my Hattori's

Hey, that's nowhere near my mid-foot!

I did both of my weekend runs on the treadmill and used my second pair of Hattori's that have yet to see pavement. Out of curiosity, I looked at the bottoms to see if the tread picked up a wear pattern from the belt and noticed some evidence of impact on the front medial side. That looked like I may still be pronating, even with a mid-foot strike. I also thought that it may just be belt dust that attached to the out-sole.

When I looked at my primary pair of Hattori's I was quite surprised to see that both heel pads showed clear evidence of wear towards the outside edge of the shoes. These are outdoor shoes and there's no other explanation except that I'm still pushing off the heel at some point in my strike.

This is puzzling because I know I'm landing on my mid-foot when I run in the Hattori's and the white EVA shows an imprint that supports that fact. Clearly there are two points of contact when I land and I'm guessing that I glance off the heel and then strike ahead of the arch. No too bad but not what I want. Perhaps I'll make a trip to a local running store in the next couple of weeks and ask to have my gait videoed. Even if my theory is confirmed I'm not sure if there's much I can do unless I want to go back to a lightweight stability shoe.

Dirty Sock prep: 60 humid minutes on the treadmill

Today's run (treadmill): 5.5 miles

The rain was coming down hard at 6:30 AM and the frequent thunder told me that the storm was close. I hoped that it would move through quickly so I could go out for a long run later in the morning. A check on weather.com showed no hope for a letup so I changed my plans in favor of an indoor workout.

If I had gone to Bethpage State Park I would have targeted 8 miles, but I knew that spending that much time on a treadmill would make me a candidate for the insane asylum. I decided that I would run for 60 minutes, including some time for warm-up and cool down. At the start, the temperature in the guest room seemed pleasant, and I had my trusty water bottle to help keep me hydrated. At the ten minute mark I still felt relatively dry and I wondered how long I would go until the sweating began.

By the time I reached the 15 minute mark I felt like I was in a sauna and I questioned whether I could really go the full 60 minutes. By 20:00 I noted that I was 1/3 my planned time and my running shorts were just about soaked through with sweat. I didn't bother wearing a shirt because I could get away without one indoors. I regretted that I'd forgotten to wear a HRM. It would have been interesting to record my physical response to the heat and humidity over the duration of my run.

I kept drinking water and by the 30 minute/halfway mark I knew that I'd be okay for 30 more. Passing 40 minutes was a welcome milestone and I reached five miles a little before the 50 minute mark. I continued for another 5 minutes and then dropped my pace and finished with a five minute cool down at around 11 minutes per mile.

I wasn't delirious when I stepped off the treadmill but I was sweating profusely and I made a beeline to the refrigerator and grabbed some Gatorade G2.  The very humid conditions, heat and 60 minutes of motion were exactly what I was after today. The conditions at the Dirty Sock 10K are usually brutal, not unlike today's. It occurred to me near the end of my run that I must be in decent shape to have gone through today's workout without quitting or collapsing in exhaustion afterward. I'm hoping that hard workouts like the ones this weekend will yield a good result on race day.

Weekend video report: The Emerging Runner Hill Challenge

Today's workout (treadmill): 24 minutes

Saturday has been a busy day and an early morning appointment prevented me from getting out for my run. That was too bad as conditions were perfect at 8:00 AM when I would have run. By the time I got free, it was already well after lunch. I had just read about TrailRunner Magazine's Hill Challenge that is going on at the Outdoor Retailer show right now in Salt Lake City. I thought that might be the perfect workout for me, given my limited time.

The TrailRunner hill challenge pits two people against each other on treadmills where they compete to see who can cover the most distance in 15 minutes while running at a 10% incline. 15 minutes seems like a short enough time to endure almost anything but I'm not a 20-something super athlete and I know my limits. Instead I did the Emerging Runner Hill Challenge which involved running 24 minutes with increasing speeds and inclines in the first half, followed by decreasing speeds and elevation during the second.

I began the run at 4 MPH with a zero incline and at 00:59 bumped to 1% and 4.1 MPH respectively. I continued this way until I reached 10% and 5.1 MPH which I held for a couple of minutes. After that I decreased by .1 MPH and 1% incline until I finished. I kept my Amphipod hand bottle filled with icy water at the ready and drank liberally throughout my workout. I was sweating profusely by the 10 minute mark and, despite the increasingly easier conditions the run still felt like hard work. 

It was great to complete a hard workout in less than 30 minutes -- perfect for the time I had. Thanks to my daughter (and camera person) I was able to file this weekend's video update. I hope to get out for a long run on Sunday. Let's see if the rain will hold off, at least throughout the morning.
