Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

\LOL at contemplating doing anything after a full 60min test.

Don't bother doing 60min indoors, it's not realistic. Do 40min. As with a number pinned on you could do 60 outside, or a 25M TT.

not necessarily doing anything, but I'll be in the way if I'm in there during the spin class.

If I can manage it then I will though, they don't give out Ironman finishers medals to wimps...
