It seems whenever I train/race really hard my achilles tendon flares up. I'm going to get properly fitted soon but I was wondering if anyone has had this problem and found that switching to rotor q-rings helped heal it. I welcome any other suggestion as to what I can do in the meantime to get myself back to 100%.

I don't know about the tendonitis but those q-rings are cool
I'm on them now and love them. My tendonitis has been much lower this year, but I think I can attribute it to focusing on spinning instead of mashing this year. Now, the rings did immediately increase my cadence, so technically it DID help my tendons.
so do you switch out the rings for normal ones on race day or do you keep them on?

I have them on my P3 (with an FSA compact crank) and rode all last year on them without problem. They wont fit on my Stronglight cranks on my Soloist, though.
are q rings basically the same thing as biopace?

From the rotorcranks.com FAQ:
How are Q-Rings different than other non-round rings such as Biopace and O.SYMETRIC?
Rotor Q-Rings help to minimize the time spent in the dead spot while pedaling. While oval chainrings have historically been controversial, we believe that allowing a rider to fine tune the chainring position offers opportunities to minimize the dead spot never before realized with conventional chainrings. The Q-Rings are elliptical; the Biopace and O.SYMETRIC chainrings are asymmetrical. The specific elliptical shape of the Q’s provide a very smooth uniform pedaling stroke; there is no sudden acceleration movement. Biopace chainrings are designed so that the maximum equivalent tooth size is at the dead-spot. Q-Rings have the minimum equivalent tooth size at the dead-spot which enables you to pass through the dead-spot quicker and with less stress to your knees. Q-Rings take into consideration static forces from your legs and the inertia of the cyclist and the bicycle. This maximizes the efficiency and comfort of conventional cranks. The Rotor patented OCP System enables you to customize the position your Q-Rings to suit your individual riding habits, body geometry, strength and position on the bike.
