    The Backyard Pump Track

    It is here. Folks thought I was screwing around the whole time. Little did I know that I was working.

    Feature: The Backyard Pump Track – Introduction | Mountain Bike Review

    Read it and comment so I can screw around some more.

    Good article, Francis. Mainstream (rider and especially local govt.) acceptance of pump tracks will be as good for cyclists as trail access. Just like children should have free playgrounds in their neighborhoods in addition to natural resources (like hiking, swimming) tucked farther out in more wild places. There is a clear synergy between the two, and fighting for one doesn't pull resources away from the other, but rather strengthens the general principle (play is valuable, riding is valuable) and builds the community, whether we're talking about getting kids outside or getting rad on bikes.

    Nice post. Pump tracks are great for everyone regardless of skill level. There is a certain art to building them correctly so they have flow. I need to look at my yard to see what is possible.

    Now I want to ride a pump track, but don't have a yard to build one in. Are there any public accessable pump tracks in the bay area?

    this track belongs to a very special/lucky person. (name witheld for privacy)
    The Backyard Pump Track-img_8847.jpg


    So yesterday I did my routine again. Drive to SC and ride for four hours, go home, eat bacon, take nap and drive my kid to SC to do some pump track til sunset. It was grueling but so worth it.

    He is happy and we get good conversation. 12-year old said he will lay out a project plan for our own pump track now that he's convinced mom it is a good idea. He said he will list our play structure for free in Craigslist and he will pay $50 of his own money for dirt.

    I got a bunch of soiltac. It looks and smells like Elmers Glue. I'll apply it tomorrow. Here's the info:

    1)soiltac: by soilworks.com Soiltac is an erosion control polymer which binds with the surface material to create a durable surface crust of flexible solid mass. Soiltac is only available in bulk and requires mixing with water in a large water trailer. Soiltac also requires re application annually and further treatments will continue to increase th surface strength, creating a cumulative effect.

    2.)G3 pathway stabilizer: by technisoil. G3 Pathways stabilizer is a similar product to soiltac, but comes in pre diluted 5 gallon totes which is far more convenient for smaller home pumptracks. G3 Pathway stabilizer requires re application annually.

    3.) Magnesium Chloride: Covering your riding surface in magnesium chloride pulls moisture directly from the air which maintains a harder riding surface and reduces dust in dry climates.

    4.)Asphalt: Covering the riding surface with asphalt is the ultimate in water savings. I built a track in rock hill northcarolina for PumpTraxUSA.com that was completely asphalted. I have attached a photo as well as the rendering of the track



    Treatment is good as Weir's track is maintenance and water free but it rides soooo good. So it's drought friendly. I just have to blower this darn thing and we're good.

    Soiltac sounds like a great solution to lock on the track. My track needs a tune up. I donated my tarps to the SDSF flow trail so they weren't available and I lost a lot of soil during the few heavy rain events this season. I think if I would have had soiltac then it wouldn't have lost so much dirt.

    Don't know. I have 5 gallons right now. The application is mix it in with 10x water and then spray it on the track. Get it to sink half an inch Coat it but not too thick so the water can still seep through.

    Some folks use Elmer's glue at $20/gallon.

    If you care about your plants. You may want to reconsider. As well, you should think twice about dumping huge amounts of this salt into your personal ecosystem as well as the general environment. This stuff is not generally toxic, but large amounts of it are going to create issues. Just be careful of your Wife's flowers, possibly your favorite tree.

    If you use good dirt with good clay content to begin with you don't need to coat it all. The clay content of the dirt is what allows it to pack up nice and firm and basically turns into concrete. When you have dirt like this all you have to do is sweep the track and then lightly water it before riding.

    I can see if you have a large track and crap dirt how using a coating would be beneficial but I don't really like the idea of dumping a ton of chemicals in the backyard where my kids play.

    You could rototill in a few bags of Portland cement or lime too. One problem with that though would be raising the pH of the soil and make it unusable for any plants down the road.

    Good dirt is the key. I just bought 5 cubic yards of good dirt that is filtered of rocks. Cost was $250. So 50 yards for an average sized track is $2500.

    Mark Weir has very good dirt clay dirt sources in Novato but he had to build his own motorized dirt filtering machine. He put in 400 yards of dirt (added to what was already there) and a whole lot of neighbor labor.

    Sweeping and watering can be a pain. Aside from the water costs and waiting, I usually just want to ride the track 5 minutes a day and this affects me getting out there.

    My base dirt has a lot of rocks and they all surface eventually.
