hy, i,m going to route a track.[my ninco has so many lumps and bumps where the grandkids walk all over it]. the space is 16ft by 6ft 2 lane. i only have 2 criteria, it must have a long straight at the back with 2- 5ft6in outside radius bends on each end of the straight. the middle can be filled with anything as long as the lap lengths are roughly equall. could someone point me in the right direction. thanks. john

An odd number of bridges and constant lane centres will give exactly equal lane lengths.
(There's more explanation here on Chris Frost's web site )

If you don't want any bridges the lane lengths can be evened up by widening the lane centres to give the outside lane a short cut.

It is worth mentioning that equal lane lengths do not necessarily mean equal lap times, although with 2 lanes the differance in times would normally be small.

The reason it puts in a crossover to equalise is that it is impossible to make the lane lengths the same with constant lane centres and no bridges or cross overs.
