On: Myths in cycling: wider tires are slower

Foot placing definitely, I love clipped in shoes for that. You don't pull though. I can ride equally as fast on flats, as I can clipped in. I've gone on 80km bike rides with people who are clipped in while I'm using flats, and it's the same. Clipped in is more comfortable, in my experience, it's not faster.

I’ve done many 100 mile+ sportives and have done both pushing down and pulling up.

You've done it just pulling up?

Both, pushing-and-pulling for rapid acceleration; as well as just pulling, often going up a hill to give the pushing muscles a rest.

Pushing and pulling at the same time takes a bit of time to get used to, but it can become quite natural after a while.
