What better way to spend the second last morning of winter?

This year sees a new course for the Dirty Dozen, and a new event. Woohoo!

The main event is a 12-ish* kilometre seductively flowing trail run on the near legendary bike trails of the Dunsborough MTB Skills Development Park, completely unambiguous - you'll be left in no doubt that the hills are all up, the rocks are hard and treacherous, the obstacles are obstacular and unforgiving, it's not paranoia, the grass trees really are out to stab you, the kangaroos and drop bears are laughing, and the easy bits...well, there's so few of those that it's not worth bothering about them. If you've never given blood for a good cause before, now's the time.

There are no road crossings or paved sections - just go to whoa dirt, mud, rocks and trail trickery. Find out more on the EVENTS tab.

The new event this year is a two person team race. One person does a 5km course, the other does a 7km course. Both runners start together (with the 12km runners) and all courses are identical for the first 3.5km. So, partner up, push each other for the first 3.5km, then run like hell on your own, to do your part for the team.

*We don't actually know exactly how long the course is, and we like it that way - as dedicated trail runners, accurate measurement is not high on our list of essential ingredients. No doubt someone with a GPS will tell us what it was, but until then, we'll just call it a dozen and get on with the serious business of enjoying a good course.

Check back here in early August for details of course familiarisation runs in the 3 weeks leading up to the event.

  1. There will be 1 drink station (water only in cups) at the 3.5km mark. This is passed a second time (near enough) by the 7km runners just before 6km, and by the 12km runners just after 9km. The drink station is officially 'off course', and you must dispose of the plastic cup in the bin provided before re-entering the course.
  2. This is a 12km event and there is no real need for gels, etc. In the interests of the environment, we ask that all competitors consider *NOT* taking any gels or other food/supplements in wrappers.
  3. In many places the course follows switchbacks. You *must* stick to the marked course and not take short cuts across the bush.
  4. Please don't use an iPod (or similar) - you need to be able to hear other runners and instructions from course marshals.
  5. All bridges on the course are single track - no passing, and please take care when crossing.
  6. All obstacles are mandatory. There are no 'A' and 'B' lines.
