What happened...The muscles on the insides of my legs, just above my knees (part of my quads) began to catastrophically tighten around the 1/2 marathon point. Over the next 20k it was a constant battle to keep a decent stride. As the race continued, my mobility decreased and my knees actually became sore as my muscles shortened and continued to lock down. I was physically forced to a walk several times in the closing 10-15k of the race.
The good news and "bright side"...I finished, didn't give up, and I'm actually feeling pretty good today (Sunday Morning).

I'm not sure what I would do differently, but I need to make sure this never happens again.
A little research would suggest e-caps/salt tablets, more electrolytes, and more to drink

Stumbling around ad I could not bend my knees and had very little mobility in my legs.
No massage after the race (didn't want to stand in line, and I thought it could do more damage than good).


Quadriceps were on lockdown after the first 21. The longer the race lasted the shorter my quads became and the shorter my stride.


I would do this race again, just need to make some better choices!
