Sudden impact is one of the nicest new cross country style trails at Vietnam. Fun and flowy with some moderate tech in the form of rock roll-overs, one or two small drop-offs and a short steep section at the end, it is a well defined Singletrack trail suitable for all skills levels, from novice to advanced depending on what speed you go. While it can be ridden in both directions, it is most fun as a down hill trail, starting on Holliston Highway, past Humpback on the right all the way down to where it joins Town Forest Trail. This trail is a must ride

Access Info

Sudden Impact has three access points. If you want to ride the whole trail as a down hill, you can access Sudden Impact from about the mid-point of Right turn Clyde. If you want to do it as an easy to moderate climb, you can start it from the bottom end on Town Forest Trail, between Optional Rocks and the Tonto turn-off. Otherwise you can enter the trail about mid-way, where it crosses over Holliston Highway.
