Still map and compass. Many run with GPS watch and download routes after. There are a few software systems(route gadget for one) where everyone can draw in their route, the system knows how long each leg took, so you can compare route choices.
Cheating isn't possible in most races as you don't know the course until the clock is running, so no chance to pre programme devices.
