Weeknight tournament, short race, most likely low entry...sounds like a good tournament to me. I wouldn't expect a much longer race for a week night tournament, especially with 8-Ball, remember, most people work early the next day. If your local players are like some I've seen around here, a race to 2 may still be lengthy in game play. If it was a weekend day event, I would expect a longer race.
Like Patrick53212 said, it gives you experience to really bear down and make every game count. Different tournaments will give you different kinds of mental experience and knowledge of varied game play, this is one for focus and playing cold (short races, even if back to back, don't really give you time to get warmed up and in-stroke).
