The usual places to find something so specific are personal training clinics or specialized medical/ rehab facilities for endurance athletes.

There are several variance as you state, but my primary endurance activities are cycling and road running which is how the test would be performed. This first test is a baseline for off season training. Another would be done at peak season training for comparison. I've also tried to set it up for the baseline to be done in winter and the peak to be done in the desert summer. Covering most of my bases.
