I think the answer on this varies wildly.
The track at Centennial (that was the name of it when it was created) was I think opened originally in 05 by a guy named Jim Keasling. Hosted the US Rotax Max finals in 07 then mostly was a solid regional track until closure in 2016. I forget what the reason was but I think a combination of factors.
The land the track is built on is a really strange use case, which I think insulated the facility from other uses (hence an opportunity) but also of course contributes to the challenges of moving forward with another venture there.
Other tracks in the region have been part of a larger facility, but even that hasn’t guaranteed ultimate longevity.
BE point is tricky. I don’t have the books from the last 2 ventures there but I presume at least the most recent one never quite broke even despite 2 years of truly commendable effort, and got to an untenable point the last year for factors out of their control. As that got closer, looking back as an attendee I now can see cues that should’ve indicated the struggles. The management of the track was competent and dedicated, but hampered by being part of a larger organization that had other business ventures that diverted their time and energy.
I think you can make a kart track viable long term but it really depends on the details. To me I would imagine that an internal building / indoor facility is more likely to be ‘evergreen’ but that is probably just my ignorance to those types of facilities.
The factor that is really unpredictable about the location of this track is local engagement. A go kart track is not a destination attraction for most people nationwide, so you’re looking at your regional and local population as being your main source of activated and (hopefully) recurring customers. The numbers of people are there, and the regional corporate centers are there. Coloradans are adventurous, like to spend time together, etc….but the region has an interesting relationship with motorsports, be it recreational or as rentals. It makes me a bit skeptical.
If the group that I know of that is really trying to get this with an RFP moves forward, they’ll have a chance at lowering investment costs by hiding it in friends businesses. Read as Paul leads the business, uses his friend Fred for contract work and Peter who does other contract work for lower costs. Nothing wrong with that. You hear these stories a lot when it comes to kart tracks across the countries. So yeah, it’ll be expensive, but one plus is the costs from a facilities stand point are relatively known and defined by anyone that wants to take it on, and none of it is (theoretically) without a somewhat solid dollar amount that’s calculable ahead of hand. The unnerving X factor is the Jet Center and their seemingly arbitrary ‘gotchas’ about the land in the past that either were not understood or not disclosed to the track operators as time went on. Having the track where it is often feels like racing in the most draconian HOA run by the FAA….but I digress.
I don’t think any karting facility is truly evergreen. Local harassment, random government over sight, and politics in the karting community can all really affect your track if not managed carefully. From being around the sport for years it seems like most tracks are constantly struggling to stay viable in some respect even when they seem to be doing well.
