Half-Marathon in Philadelphia
Be warned it's a long read, but hey, I had to run 13.1 miles.
I stand with my back against some temporary fence. Darkness is giving way. It’s not terribly cold, but chilly enough when wearing a thin tech tee shirt, a kilt, a knit cap, tube socks converted into arm warmers, 2 pairs of cheap Dollar Store gloves, compression sleeves over the calf muscles, toe socks and a worn-out pair of Xeros. The Xeros in fact have some duct tape patches in order to protect the toe socks from unnecessary friction. 5 more minutes and I will remove the Xeros and toe socks.
I look around behind me. The Philadelphia Art Museum is impressive, maybe because I’m too close, having been herded into the purple corral. When registering for the half at the Philadelphia Marathon, I was...
How Much Does Shoe Weight Affect Performance?
By Dr. Jack Daniels
As a matter of fact I did the original research on shoe-weight factor, when I was working for Nike in the early 1980s and our research was presented at the World Congress of Sports Medicine in Vienna in the early 1980s. We found adding 100 grams to the shoe increased the aerobic demand of running by 1%. Now 100 grams is about 3.5274 ounces, so each ounce changes the cost of running about 0.2835% To continue reading, please visit: http://runsmartproject.com/coaching/2012/02/06/how-much-does-shoe-weight-affect-performance/

It's a done deal. 103 miles in 30 hours and 40 minutes. Course ran a little long and I got off track a couple of times (completely my fault, part of the adventure). I did have a goal time of a sub 30, but a few things slowed me down. A finish is a finish and I am happy with any time.
Brief summary: The waiting was the hardest part including not much running the weeks before. This led to the common mistake of going out too fast. I broke the race into 25 mile sections.
The first "marathon" went well, but too fast. The trail was smooth and the excitement high. The miles few by but knew I had worked my legs too hard too early. 5:15 for this section.
The second "marathon" was rough, but not too bad. I got behind on nutrition and fluids and got...
