Trailbuilding - Looping SingleTrack

Hey All,

I've recently moved back out to my parents place who have a 2.5 acre acreage. They are sick of mowing so much grass so they have let the back half to go wild and are going to plant some random trees. I have approached them about building a dirt track out back for my bike. Thankfully they have agreed :-)

Now i need to figure out how to build this and what is going to be best for the space i have. I joked that i was going to get the niebour to bring over his bobcat, but in all seriousness that is an option :-p I've done a wack of investigating and done allot of reading on IMBA but most information is trail building out in the woods. I'm NOT wanting a BMX oval but something that will have some good rhythm sections, a drop, and what have you, but in a looping fashion, pretty much single track.

So i have a good idea on HOW to build it, what materials to use and the best methods to do it. What i don't know is the best formula for an effective track. The land is pretty flat with a slight grade down on the one side, and only a small area is treed. I will post some pics.

I've tried to find some sites that talk about the theory of track building but haven't found anything that answered my questions. I hope what i'm trying to do was conveyed here lol i can get a little wordy at times.

You can build a helluva jump track with that much land and a bobcat.

It's all about what kind of riding you want to do. If you want really fast flowy sections, you can basically plow straight through the area a couple of times with various jump lines. This will produce shorter tracks with high speeds. On the other hand, if you want a long trail, you can make a trail that has tight turns, but speeds will be significantly lower.

I would advise you to survey the land to first see if there are any natural elements that you could use. You should also think about what speeds are required through certain sections (for jumps), and what type of jump you want. A table will generally be safer than a gap, but will require more effort, etc.

Is it a square, flattish 2.5 acres? A crude drawing would help to give us some ideas.

Definitely spend some time out there surveying though.

With that much land you could do a pump track AND the singletrack loop. Sweet!

Thats kinda what I was thinking as well. Make a pump section that flows into a couple/few jumps then another pump section into a ladder bridge/stunts to drop , back to a pump sections, etc etc etc

With the cat and that much space you can build a sweet track.

i don't have the full 2.5 acres at my disposal, i'd say about 1/2 acre. My parents have an aerial shot of the property somewhere so I'm trying to track that down then will start sketching some designs out.

Its been awhile since i've gone hard on my bike, been outta the scene for awhile now. If some of you have some ideas as to how to transition the course from section to section, what can have a good flow please let me know. I'll get more info up ASAP as far as area and plot design but any ideas would be great!

Lee McCormack's book (see santiago's link above) is full of details on drainage, design, and construction, and contains some suggested track layouts as well. The extra time and effort you'd have to put into building by trial and error is well worth the cost of purchase of the book IMO.

I've never built a track before (always been very interested, but with no land) but I like this advice. I wonder if you could just get on your bike and head straight into the land to see where it might take you. You might find some features that already exist that would be a good addition to your track.

That pump track does look sweet, though . . .

In addition, since it will be short, I'd design it so that you can ride it in both directions, so that you don't get bored as quickly. You can also accomplish this by having lots of sections with teo or more possible lines, parallel trails, etc.

this is great stuff! i'm going to go do a dry run and get a better feel for the land although it is pretty flat, we'll see what i come up with.

I'm gone to waterton this weekend for a little biking trip!!!! Woot!
