Today is my birthday. It’s also the summer solstice, the longest day of the year (in the northern hemisphere), and a full moon to boot.
We don’t get a full moon on our birthdays very often. On average, we Earthlings only get a full-moon birthday every 19 years. We don’t get to be 81 on our birthdays very often either. So I’m celebrating.
So what am I doing today? Well, in between standing at my computer writing stuff, I am rowing the Concept 2 “Summer Solstice Challenge.”
The Challenge is to row 21,000 meters today. The Challenge is a worldwide event open to everybody. All you need is access to a Concept 2 rower with a chip or memory card that records your meters.
You can choose to do the whole 21,000 meters in one sitting (ugh) or you can break it up into smaller pieces (yes). I chose to do ten sets of 2000 meters followed by a finishing row of 1000 meters. As I write this, I have just finished my fifth set. So I am about half way there. [Read more…]
Today, I rowed 500 m in 1:49.6 for world first place in age group. – Ed
In a few months, I will begin a health and fitness coaching group focused on keeping fit as long as possible. If you are interested, be sure to be on my email list and tell your friends.
There is a world of things I can tell you about. I spend very little time exercising but I make the time count. Follow me on Twitter here.

In 2006, when I lived in Sacramento, I used to hang out at the American River College (ARC) track. One summer day, Coach Mike Reid, ARC track coach, invited me to train with his track team, which is like driving your family car in a NASCAR race.
Though the college runners were way beyond my speed grade, Coach Mike and his assistant Coach Ray, helped me improve my running speed well beyond what I thought would be possible.
Recently, Coach Mike Reid earned a well-deserved credit. In 2010 and 2011, he coached Sacramento sprinter Diondre Batson, now the “World’s fastest man in 2013“. Diondre Batson credits Coach Mike Reid with encouraging him to continue his track and field career after incurring an injury in a high school track event.
Running under Coach Mike, Batson set the ARC records for 100 meters (10.10 seconds), 200 meters (20.50 seconds), and with teammates Bracin Walker, Greg Turner and Keven Brown, the 4×100 meter relay (39.78 seconds).
When Diondre Batson wins the 100 and 200 meter sprints in the 2016 Olympics, you will remember he began his track career under Coach Mike Reid. [Read more…]

How does 1:46.3 compare to my good competitors?
The Concept 2 website allows you to register and enter your rowing time and your age and weight category and then compare your time with the best rowers in the world.
Concept 2 began its 2014 fiscal year on May 1. Since new competitors will beat my 2014 time, we also compare my 1:46.3 time with the 2013 competitor times.
- 1st in world for ages 75 to 79, all weight categories.
- 4th in world for ages 70 to 79, lightweight division. [Read more…]
There are no manned rockets or airplanes built by any government in the world that can accelerate from a standing start as fast as a Top Fuel Dragster or Funny Car!
One top fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows of stock cars at the Daytona 500.
It takes just 15/100ths of a second for all 6,000+ horsepower of an NHRA Top Fuel dragster engine to reach the rear wheels.
Under full throttle, a dragster engine consumes 1-1/2 gallons of nitro methane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced.
A stock Dodge Hemi V8 engine cannot produce enough power to drive the dragster’s supercharger.
With 3,000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near-solid form before ignition.
Cylinders run on the verge of hydraulic lock at full throttle.
At the stoichiometric (stoichiometry: methodology and technology by which quantities of reactants and products in chemical reactions are determined) 1.7:1 air/fuel mixture of nitro methane, the flame front temperature measures 7,050 deg F.
Nitro methane burns yellow… The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.
Dual magnetos supply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.
Spark plug electrodes are totally consumed during a pass. After halfway, the engine is dieseling from compression, plus the glow of exhaust valves at 1,400 deg F. The engine can only be shut down by cutting the fuel flow.
If spark momentarily fails early in the run, unburned nitro builds up in the affected cylinders and then explodes with sufficient force to blow cylinder heads off the block in pieces or split the block in half.
In order to exceed 300 mph in 4. 5 seconds, dragsters must accelerate an average of over 4G’s.
In order to reach 200 mph (well before half-track), the launch acceleration approaches 8G’s.
Dragsters reach over 300 miles per hour before you have completed reading this sentence.
Top fuel engines turn approximately 540 revolutions from light to light! Including the burnout, the engine must only survive 900 revolutions under load.
The redline is actually quite high at 9,500 rpm.
Assuming all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs an estimate $1,000.00 per second.
The current top fuel dragster elapsed time record is 4.428 seconds for the quarter mile (11/12/06, Tony Schumacher at Pomona, CA ). The top speed record is 336.15 mph as measured over the last 66′ of the run (05/25/05 Tony Schumacher at Hebron, OH ).
Putting all of this into perspective:
You are driving your average $140,000 Lingenfelter ‘twin-turbo’ powered Corvette Z06. Over a mile up the road, a top fuel dragster is staged and ready to launch down a quarter mile strip as you pass.
You have the advantage of a flying start.
You run the ‘Vette hard up through the gears and blast across the starting line and pass the dragster at an honest 200 mph. The ‘tree’ goes green for both of you at that moment. You will finish your quarter mile in 4.5 seconds. The dragster launches and starts after you.
You keep your foot down hard, but you hear an incredibly brutal whine that sears your eardrums and within 3 seconds, the dragster catches and passes you.
He beats you to the finish line, a quarter mile away from where you just passed him.
Think about it, from a standing start, the dragster spotted you 200 mph and not only caught you, but nearly blasted you off the road when he passed you at a relative speed exceeding 100 mph, within a mere 1,320 foot long race course or the distance of one lap on a sports track.
…… that, my friend, is ACCELERATION!
