Finished and took a long shower, even with preparation it's fucking hard. My legs and buttocks are killing me. Luckily I have good shoes so my feet are pretty good considering. The last 5km I had to slow down a lot cause my heart was constantly going over 182 bpm, except for the last stretch where I tried to go allout and had over 200 bpm, close to my max (last time 205). Now going to eat like an animal cause I burned over 3000kcal. A full marathon is a bit too long for my tastes.
