The opportunity to build new trails is a rare one. Usually, we
cyclists only get to solve problems on existing trails. But, we've
realized that it's the initial design that is the most
important part of building a new trail. If the design is right, then
all other problems can easily be solved without having to relocate a
section of trail. The two big keys to successful trail design are
to always try to minimize natural (erosion from rainfall and water) and
user impacts.
A good place to start trail building (after
obtaining permission from the land manager) is to decide where the
trailhead will be located. From the trailhead, start with a short
3- to 5-mile loop (loops are preferable to out-and-back trails) to
create your beginner trail. Keep the grade at 5 percent or less over
the bulk of the loop; concentrate more on scenery than challenge.
If
you have a linear piece of property, more difficult trails can be
located farther out, building off the back of one loop to another. This
stacked-trail design gets more challenging as you get farther out,
which helps keep less experienced riders away from trails that prove
too challenging for their abilities. It also allows you to use the
mileage from one loop to another to increase the total distance over
the entire system.
If the property is not suited to this type of
layout, consider separate loops for different levels of ability. We
recommend the following trail guidelines: 36-inch-wide trail for
beginners, 24- to 30-inches wide for the more experienced; and for experts, 12-inches wide.
Keep these rules in mind while designing and constructing trails:
Identify all the places you want to avoid (property lines, ecologically
sensitive areas, etc.) and all the places you want the trail to
go (i.e. trailheads, scenic vistas, cool rock areas, etc.) before you start.
Use natural features (large rocks, sharp turns, natural dips, etc.) to provide challenge
rather than steep grades, which easily erode.
To prevent erosion (you want the trail to last, don't you?), follow
the land's natural contours and don't build on fall lines (straight up
and down the hill). Water will run right down the trail.
Keep your average overall grades to 10 percent or less.
Most importantly, spend as much time as possible looking at what the land
has to offer and planning your trail system before you build.
Your buddies will thank you for it later!
