Hmm, I made a some calculations and 1:08 would require (eg.) 20 sec first lap (250m) and then maintaining 56.25 kmh for the rest.
20 sec first lap could be just within reach
in theory (or looking at my workouts, which are not from full stop but from some sort of a track stand). In reality I don't know how much time is lost in actual start. And then the rest... no way. Assuming top track, with top tires (0.002 crr), my tested CdA (how well that could held trying to max power?) of 0.27 it would require maintaining about 660w average for the rest 48 secs and after all out 20 secs, I'm already fried. It would be quite like Swampy very well described earlier
.
Well, nice speculations in lack of actual doing, waiting for next summer to come (last two rides have ended up in a hail storm
)
