That was immediate thought too.
Also...
The cyclists are timed each time they ride the ParkRide ... Results are emailed to participants, allowing them to track and aim to better their times, as in parkrun.
That's getting into the realms of TT-ing, and could encourage irresponsible riding as people try to push themselves. Also - would there be legal issues with organising a cycle
