The tyres gave out a satisfying crunch as they cut through the gravel on the fire track, a plume of dust spread from my rear wheel and the sweat began to dry on my brow as the trail dipped down steeply. The track was clear in front of me as far as the eye could see. I pushed my backside behind my saddle and forced my bike hard into the oncoming corner. I was flying, taking air, whooping and hollering with no one to hear my juvenile screams. I was totally alone in the Australian bush with my mountain bike and miles of trail all to myself! I was in heaven!
