Finished the race yesterday in 40:29. Over 14 minutes faster than the last time i did it! It was even tougher I think because the terrain was much harder to navigate and the obstacle were more intense. Loads of fun though.

I did no training beside crossfit. Definitely going to be under 40 next time for sure.
