    online track design tool

    I am going to build a pump/jump track and have a 120 x 60 space. This is what I have designed for the space any thing you think I should add / change?



    Sorry if you can't read my writing, if something needs clarified, just ask.

    You're leaving the middle empty. Is that intentional, for further development, or what?

    There's also nowhere enough room on the back side of the corner berms for the back of the berm, regardless of the berm height. I don't think 5' tall berms are unreasonable on a pump track, and 3' is kind of about the minimum. Which means you need between 4' and possibly 8' depending on your soil, to have a back of the berm you're not doing constant maintenance on.

    I've also learned to mark my turning radius. Bigger is better if you've not done it before, but you can get too big. Check out cmc's comments here on what works for turning radius:
