Brutal 8.5
Today a full day of 9-hole golf, played the front 5 horribly and straightened it up with 4 straight pars to finish. The trick is I finally figured out what a "swing plane" is and am swinging that way without "breaking" my wrists on the backswing. It definitely feels a bit wimpier but the balls are flying straighter, and without the spin, farther.
I only did a 4 miler Friday in hopes of a long run today, so after golf I got ready for a nice "warm" afternoon stroll. I basically did my usual route through the neighborhood and through the Oakland Cemetery, but added a small detour for a total of 8.57 miles. ALL SAID IT WAS THE WORST RUN I'VE HAD A IN WHILE. I felt horrible all the way till about mile 4 then just felt weak and fatigued. Looking back my breakfast today consisted of coffee on the way to golf and lunch was some chips and salsa. Let's hope that's what did it.
I took a few pics of the cemetery when running through (been meaning to do that) and will upload them when my desktop computer gets its new monitor this week (thanks Dell).
For the Garmin Forerunner crowd, my neighbor and I ran together. He has the 305, I have the 205. We were careful to start and stop them exactly the same time and of course we ran together. His recorded us going 8.67 miles, mine 8.57. The only difference was that mine was set to "auto pause" when we stopped for water and photos, and his kept recording. I guess that's what did it... or do you think the 205 and 305 have different algorithms?
On-On till next time
Calories Burned Running Hills (Controversy)
Top Rated Otolaryngologist, Ballon Sinuplasty, Sinus Surgery in Atlanta
A buddy and I have been debating the caloric expenditures of running hills. After a little research it seems there is a reasonable discrepancy out there about just how much "work" is done when running up and down hills.
There is a an old-school formula out there that most treadmills and exercise calculators use that take your calories burned at a given pace and multiply that by the grade (or incline) to get the marginal increase or decrease in running hills. For example:
[kcals @ 5% incline @ 7mph] = [kcals @ 7mph] + [kcals @ 7mph] x 0.05
To me it seems this equation has a few shortcomings and assumptions:
- Assumes that the relationship between CALORIC EXPENDITURE and GRADE is LINEAR. So going from 20% grade to 25% grade is just as hard as going from 1% to 6% grade.
- Assumes that running downhill is easier than running uphill, and to the SAME DEGREE. So running downhill 15% is just as easy as running uphill 15% is hard. Weird double speak I know.
- BOTTOM LINE IS that if you run in a loop at a steady pace all your uphills will cancel with your downhills and you get no calorie calculation credit for any "hills" that are in the loop, no matter how big. I think most can agree that a hilly run is almost always SLOWER and harder than a flat run (we should get credit!)
What they found is very complex to interpret, however Figure 1 seems to make it most clear to the "rest of us":
- The increase in calories burned going uphill DOUBLED when the grade increased by only 20% (for example going from 10% to 30% grade energy expenditure went from 5 to 10). By the traditional calculation our calories burned would've only gone up by 20%, rather than 200%.
- When running downhill, energy expenditure seems to follow the traditional rule until we reach about a -17% grade. At this point it actually gets HARDER to run downhill than uphill.
So the net result of all this is that when running in hilly terrain we are burning far more calories than our old-school calculators are telling us, even if we run in a loop where the uphills "cancel" the downhills.
To go a step further I took a 1 mile loop near my house where I run up (and down) a big hill. Using the traditional calorie calculation I'd burn about 130 kcals (based on weight and steady pace). If I add in the corrections for hills from this study it bumps my calories up to 220 (about 70% more; note that doing this calculation was tough and used excel, I will spare you for now).
So the challenge is twofold: 1) repeat this study a few more times under varying conditions to validate it, and b) change the fitness calculator world to account for this.
A third challenge is underway and might just be patentable, so I will hold off on unveiling it for now.

Strange Thing Happened...
Strange thing happened on the way to the blog: I did a self-search for thismanruns at technorati and found a) that I have NOT been automatically pinging my posts so technorati barely knew me but more interestingly b) an off-beat mashup-advertisement-only website about elliptical machines apparently borrowed my most recent post and presented it like thier own original content. There is probably a techno-savy term for this, but I don't know it. Apparently they have a bot out there that searches for posts that mention "elliptical trainer" or the like and then they copy those blog entries into their own feed. This gives the appearance that they are hosting this awesome blog with postings from elliptical experts everyday.
Also on the way to the blog you'll notice I made a few layout changes. I hacked the Blogger template and made the two columns a little wider so there isn't so much wasted space on the sides. I also added some new buttons, like the " Digg This" and one for the Complete Running Network Blog Family. Additionally I got this new piece of blog-flare, the Romlet. I'm still not sure what the Romlet is. It does something to keep track of how many of their tracked sites link to you. It was billed as being some kind of tool to build a blog social network or something, but I don't see how. Unless I find it useful in the next week or so I will kill it.
MOST INTRIGUING TONIGHT was around 7pm when I was at a stoplight on the East side, facing south I saw THE BIGGEST METEOR EVER. It looked like it could've been a missile heading to Earth, but burnt out about 20-degrees off the horizon. Mind you it was so bright it was very clear and bright in the middle of the city with lots of ambient street lights around. I even thought it could've been a plane or something going down. It started dim like most shooting stars then brightened up, got a tail, got dim then got real bright, like an explosion and dim again until dark. Lasted about a second. I've been out at 3am to "meteor showers" before in rural areas and never saw one this bright. Cool is all I'm sayin'.
In running news I did my usual weekday-workday routine yesterday, this time adding an extra half mile or so. I will probably do the same Friday. Still chilly here, but most of the cold is coming from the whipping wind.
And yeah, Brian, lets plan on a pre-ING run - maybe 3/15? (early AM) Everyone else invited of course...

Naples 1 and 2
This past weekend one of my medical societies had thier annual meeting at a luxury hotel down in Naples, Florida. I took advantage of the climate (both social and meteorological) to partake in both cocktails as well as a run on the Naples gulf shore.
