Most I've ridden in one day on platforms: 85 miles
Most I've ridden in one day on clipless: 54 miles.
Number of bikes I have right now with clipless: 0

I took 'em off. They were fun to learn and master, but honestly I didn't find they enhanced my bicycling joy all that much.

Don't stress about it, Catrin. Seriously. You may find that once you learn them, you discard them just like I did. You may find that you love them more than chocolate. It really doesn't matter.

It. Doesn't. Matter.

Ride your bike. If clipless freak you out, don't force yourself. Get a pedal wrench and learn to use it, change back and forth, and do what you want and when you want. They are not required. They are not a badge of courage. They do not mark you in some mystic way.

They are only pedals.

Ride.
