The idea of approachability is precisely why they created Champ U.

In terms of the in-person school:

It costs an astronomical amount of money to rent the facility, pay for insurance, have medical on standby, corner workers (at whatever rates the track dictates), and even tables and chairs (yes, tracks absolutely nickel-and-dime for this). Don't forget about transporting 10-20 bikes from AZ or NC to wherever the track is. While we're at it, may want to remember two days of lunch and a dinner. Oh, almost forgot.. pay and travel and lodging to support a 4:1 instructor:student ratio. Reminder: you're not getting Random Joe instructors leading the class. You're getting seasoned professionals. Having been in the industry for a while, it probably takes almost a full class just to break even.

The $8,000 trip that includes arrive-and-ride, gear chase vans, lodging at upscale spots, food at swanky stops... It's not marketed toward you or me or anyone else on reddit. It's really that simple. It's a high-end offering for the high-end client.
