A few familiar MTBO names in here
http://racetecresults.com/Results.aspx?CId=11&RId=...
Adrian Jackson running 2nd
Steven Cusworth 18th
Looks like they ended up in those places over the full race
Dave Nairn and Jon Gregg (10th and 13th) came out to WA MTBO events in the early days.
AJ and SC also both used to do MTBO. Looks like the natural progression for me.
