I've been enjoying my offseason so far but am champing at the bit to get back on the steed. Are there any chainlinkers on here that do VQ? Thumbs up? Down? Is it just a glorified spin class or is it worth the investment?

As a bit of background I typically do endurance rides and average 125-150 miles a week in the summer. I'd like to be close(r) to riding shape when the weather turns in March (and especially when the Arcadia Brute comes up in May). Last year it took me 8 weeks to get back up to century shape and would like to cut that down significantly.

Also, benign procedural question. Do you leave your bike at VQ? Or do I need to lug to load it in my car and drive it there for each session? 

Thanks!
