Who would like the Dirty Duathlon event?

A lot of triathletes , Runners and Mountain bikers quickly adapt to the Dirty duathlon, get hooked and take up paddling so they can do the Ultra…Or if you hate all things water, then this might be the one for you!

  • a few small wood logs across the track which have been cut or built up to allow easy roll over.

  • a few cool jumps which can be hit to launch by advanced riders or simply rolled over for the less experienced
  • a few small drops

Anything that is considered at the upper level of technical for this course will be marked with a difficult terrain sign or ! sign , Images of these will also be shown at safety brief with tips on how to best attack them.

The hills are a relatively easy climb by comparison to a lot of other ride locations we have, relatively short and not super steep climbs

Main riding surface is Dirt and limestone with only a few small sections of gravel and a tiny rock garden or 2 to contend with.
