Indoor training facility

If you were to set up a triathlon indoor training facilty, i.e. a gym designed for triathletes, how would you set it up? What equipment would you use (exercise bikes, weights, etc.)

Indoor cycling in the home is far from ideal, since one is staying in place and generating a lot of body heat and sweat. One needs a designated area that is well ventilated to provide a cooling effect.

I’ve actually given a lot of thoght to this, since I’m planning a basement gym for winter fitness.

Endless Pool
Lemond Revmaster
Lifefitness club quality treadmill
Smith machine with adjustable bench.

I think that’s the most bang for the buck/space.
