I travel about an hour to PTC Perth. It's not very far away, just our highways are shit.
If it's a place that you enjoy, training becomes that much more enjoyable and you're much more likely to not skip a session or find justification to stop. I could travel an hour each way to PTC Perth any day of the week, but before it existed, really had trouble going to Fitness First with any sort of regularity which was walking distance away.
TLDR: It's worth the travel.
