The unsurfaced sections of the trail are very muddy at the moment. So bad that you stand a good chance of not being able to pedal once the mud collects on the bike.
The best way to help fix this problem is to come on our build days. We estimate that another 8 days of action will see all of the trail surfaced. As it is the mud is spreading onto good sections and will gradually ruin them.
Unsurfaced sections are shown in yellow in the map.
