One key factor is the rigidity of the rails. I tested with PVC Shed 20 and it is so-so, and that’s why I suggested Schedule 40. It’s still relatively cheap and readily available. You might test a length of Schedule 40 and Schedule 80 and see if there is a noticeable difference.
Another key factor is the number of trucks. I purchased a large pack of new rollerblade wheels on eBay for cheap. Just drill a few more holes and add a few more wheels to distribute the weight and reduce deformation of the PVC. The rails will not have any turns, so you can evenly distribute the trucks down the length; no need to gang the trucks at the four corners.
Yes, just get a piece of foam and staple some fabric around the edges.
That’s the hard part, and why I would also consider a rail-less design. Perhaps just build a really fast sled with rollerblade wheels fixed in a straight line that is the right height and weight and practice in a parking lot. Would be even better if you could find a lot with a suitable slope. Of course, you would also need a simple braking mechanism.

Christopher, I think that I could probably do without hopping on the sled actually. It would be hard to slow down by going downhill with the sled, but I think I could probably just stand up and try to decelerate as much as possible. Sure it wouldn’t be as legit, but if this was the best access to sled pushing that I had, then I’d be fine with it.
