Depends who's rules you use for a 'record'.
If it's a self-claimed "I'm the fastest unsupported Belgian on a road bike to wheelie four times around the carpark of this Tesco on a Sunday" then whatever but orgs like Road Records Association have rules for attempt timings so you can't start two riders too close together.
Guinness WR have their own rules too, although they seem to ignore them/make them up as they go along.
Start a fake showdown. Bikes at dawn. One record. Two men. One vision.
