Bags & Valuables

We must ask that you leave ALL your valuables in your car, and we will have a safe place for car keys.

Footwear & Clothing

All runners must wear suitable footwear (running trainers or trail run shoes are fine). Shoes with spikes are not permitted. Runners should be aware of weather conditions on the day of the event, and wear suitable running clothing. A change of dry clothes is also recommended.

Course Map, Navigation and Marshals

There will be a large course map at the registration area before the run starts. There are plenty of arrows placed on the course, as well as distance markers at every 2km. Marshals will be stationed at every ditch and obstacle.

Water Stops

There will be two water stops throughout the course, at ditch 7 and between ditches 10 and 11.

Washing Off

There will be outdoor showers available at the end of the run to wash off the worst of the mud! Please bring your own towels and face wipes.


Toilet facilities are provided at the registration area. There will also be portaloos on the course itself, by the water stop.

Accidents & Injuries

There will be a full medical team on site to deal with any accidents and injuries.


Spectators will be able to see the start and finish, and follow the spectators' walk. The walk visits some of the best obstacles on the run, and there is also a looping 'hop-on drop-off' tractor and trailer ride that follows the spectators' route.


There will be bacon/sausage sarnies and tea & coffee available from 8:30am to 10:30am (before the runs start). There will be a barbeque during the event, supplying Hook & Son beef burgers, with salad. Chilled water, milkshakes, and alcoholic drinks will also be available. Runners will also receive their very own Mad Marsh Run T-shirt, medal and a glass bottle of Hook & Son fresh organic milk!


Free photos of the event will be posted on our Facebook page.
