The erosive effect of water on poorly designed or maintained tracks can be severely compounded by repetitive skidding. Tracks with a gradient of 15-20 degrees should be gravelled and compacted. The track tread should be maintained to at least 0.5m wide and vegetation be kept clear to a width of 1.5m to ensure the riders tyre prints do not all overlap. Without eliminating the challenge of the ride, obstacles should be removed where they force riders onto the same narrow strip of track. Riders tend to veer towards the outside edge of narrow tracks, so soft track shoulders should be reinforced, especially where the track comes out of tight corners.
Large events are an effective way of ascertaining the likely long-term impacts of bicycles.
The Western Hunua Loop in particular would make an excellent event course. Local clubs should be vigorously encouraged to participate in track work. Umupuia - This area is unlikely to attract high use or incur significant impacts. Ensure loose gravel is bound by clay. Maintain steps on gradients over 15 degrees and before blind corners.
