Typical races here can be widely varied. The first was a 5.5km (2 laps) loop on a ski hill with only up or down hills mixed with single track.
The next two races I did were only on fire roads (42 km and 12 km - mud)
The most recent was an awesome 8 km loop (3 laps) with 50% of quite technical single track and the rest gravel and sand track.
