Flash, Send and Project: What They Mean in Bouldering

On this page

Someone points at a climb and says, “That was my project. I sent it today.” They were working on it, and today they completed it. They are not saying it was their first try.

The short answer

Word What the climber means
Send Complete the climb from its start to its finish without falling.
Flash Send the climb on your first attempt. You may have watched someone else or received advice beforehand.
Project A climb you are working on and have not yet sent. It might take several attempts or several sessions.

A flash is also a send. A send after earlier unsuccessful attempts is not a flash.

Three things you might hear

“I flashed the blue one.”

Leah watches a friend climb the blue problem. She then completes it on her first attempt. She has flashed it: watching first does not rule out a flash.

“I sent it on my fourth try.”

Omar comes off the same climb three times. On his fourth attempt, he climbs it from the start to the finish without falling. That is a send, but not a flash.

“That orange one is my project.”

Nina has tried the orange climb and wants to come back to it. She has managed some of its moves, but not the whole climb in one go. It is her project. When she completes it, she can say, “I sent my project.”

What about a first try today?

If you tried a climb yesterday and complete it on your first attempt today, it is still a send after earlier attempts. Calling it “first try today” makes that clear; it is not a first-attempt flash.

You may also hear onsight for a first-attempt send without prior information. Beta means information about how to do the climb, such as advice about the moves. This guide uses flash for a first-attempt send where prior beta is allowed.

Check the distinction

You watch someone climb, then finish it on your first attempt. Can it be a flash?

Yes. A flash allows prior information, including watching someone else.

You finish on your first attempt today, after trying it last week. Is that a flash?

No. You have sent the climb, but it was not your first attempt on it.

You can do all the moves separately but have not linked them from start to finish. Have you sent it?

Not yet. Doing the separate moves is progress on the project; a send puts the whole climb together.
