Mud Mash – Tougher than the tough ones, and more fun than the fun ones: the All Out Way! The Mud Mash is a 5k and 10k mud run with dirty obstacles, wall climbs, lake scramble, hay bales, slip and slide and of course a huge, nasty mud pit. Not to mention some tough trails that will be even tougher when you’re wet and MUDDY.

Great Obstacle Course Run

Oct 31, 2013 by Bronc

OK, so most of the mud was on the bottom of Lake Laguna, but this was a great obstacle course run! Loved the elevation climbs and the extra mile. So much better than the average 5K mud run. Well organized and executed. Good time was had by all. We'll be back next year.


Muddy Fun

Sep 28, 2013 by Michelle Fletcher

I couldn't be more excited for this race! It is one of my favorite races ever (only trumped by the same company's 12 hour Adventure Race)! I've run this course every year and somehow they find a way to shake it up and make it even more fun than the year before. Their T-Shirts rock, the obstacles are fun and challenging and the course is beautifully brutal. Great for all levels, I did this course in top shape and got a kick butt workout and did it 8 weeks after having a baby and just had a great time with all my friends. I love All Out Events and their Mud Mash!
