I'm not trialing much, but the furthest I've gone is about 2.5 hours. Sunday will be almost two hours.
If I have to be somewhere at least that far (2-3+hours) AND the trial starts at an ungodly hour, I am more than happy to get a hotel for the night before. Stuff like rally, usually there are two trials a day, and two days of trials. So it makes sense to go for a whole weekend to try and get some legs done. I'd rather make the drive once and stay in a hotel for the weekend than make the drive twice for one day each, yknow?
