Ride Frequency
UrbanHop is opening a subscription product to a small beta, and the invitation list is riders who have used the platform more than once — two or more trips they actually took. Someone who booked twice and cancelled once has told the platform very little about whether a subscription would suit them, so cancelled bookings do not count towards the threshold.
The invitations go out under the riders' names, in a sequence the growth team can work down and tick off.
rides — one row per booking. rider_id points at a row in riders and driver_id at a row in drivers. distance_km is the trip length in kilometres and fare the price in dollars; both are recorded when the booking is made, so a booking that never happened still carries them. status is either completed or cancelled. ride_date is the day the ride was booked for.

Both tables already exist in the database — there is nothing to create or load.
Task: Write a query that returns a single column, name, listing every rider with two or more completed bookings, sorted alphabetically by name.
Example output
If the three riders clearing the bar were called Cleo Barnes, Elena Ford and Hugo Marsh, you would get:
| name |
|---|
| Cleo Barnes |
| Elena Ford |
| Hugo Marsh |
