After having it for two weeks, this afternoon I finally got to take the MTB out for a spin in the dirt. It was only for an hour or so, but I had a great time. I stuck to the fire trails near home for my first ride, and I did multiple laps of a fairly easy course just to get the hang of the gears, brakes and basic handling etc, but that was enough for my first workout. It was good fun, but it was hard work and I reckon I'll have to be careful that I don't blow my knees apart by doing too much too soon. I wouldn't imagine I'll ever be fast on a mountainbike, especially on the technical stuff
