Pretty Muddy is a 5K female only obstacle course that is held at multiple locations nationwide each year.

CRUK asked us to develop a number of new inflatable obstacles and work alongside them at their nationwide series of fundraising events. The giant inflatables needed to be installed, run and removed in a single day.

What we did

We designed, tested and produced 3 different types of obstacles, including ‘Mission Inflatable’ hurdles, ‘Get Down and Dirty’ mud pits and ‘Mud Chute’ slides.

MOF installs and maintains them at each event, as well as providing staff to ensure the safety of participants and guarantee they have a muddy good time.


The event series has been so successful that #PrettyMuddy has seen over 400,000 women take part in 142 events.

Participants are sponsored to raise money for CRUK’s ongoing fight against cancer and, to date, we’ve helped raise over £30 million for this incredible cause.
