I've recently bought my first MTB (29er hardtail) after a few years of recent road cycling and many years of riding kids bikes long ago during a misspent youth when our house backed onto "the bush". I think what I'm currently doing could loosely be termed Cross Country? As part of my triathlon training program I'm now riding loops of single track which have just as much down as up. I'm considering entering an off road duathlon (run/ride/run) which will be mostly on fire trails and dual track, but I'm training in single track for a few reasons, fun being one of them. I'm almost 48 now so I don't have as much fearlessness as I did when I was a teenager, but I am finding a sense of achievement if I can negotiate some of the simple obstacles on the trails (at Mt. Gladstone in Cooma) better/faster/smoother. What's the one tip you would give a newbie to help them become a better/faster MTB rider?
