not sure where the waking up problem comes from.. i've been using the vector pedals for sometime and they work fine.. before i get on the track, i wake up the pedals and turn the head on and then start the timer before i get on the track.. the bike could sit for 20 minutes, doesn't matter; once i start rolling, i get data.. never had them go back "to sleep".. do powertap P1 pedals act any different? my main concern is the pedal clearance.. the P1s have a battery compartment on the bottom.. it looks like i'd be ok but maybe someone has used them on the track and can confirm clearance isn't a problem.. i have 3 bikes i use regularly so 3 power meters would be too expensive for me..
