Peace Run.

A lot of folk think I am nuts to do this rowing trip, but in Renmark I met a group doing something I find more remarkable and harder. Take a look at

These people stayed at the same hotel we did in Renmark, and I chatted to them at breakfast. They are running from Uluru to Canberra, via Adelaide and the Murray Valley. This is a long way, hot, dry and, in my opinion, the Sturt highway section is scary and not fun. Good luck to them. I hope to be in Canberra when they finish.
