Run through and walk through both describe going over material together, and both use the same "verb + through" shape. The difference is speed and purpose: one is a rehearsal over material already mostly known, the other is a careful first pass for someone learning it for real.
"Run through" means a fast pass over material the listener already mostly knows -- used to rehearse, check, or refresh, not to teach from scratch. "Walk through" means a careful, explanatory first pass, built for someone who genuinely needs the sequence explained.
A quick refresh vs. a real first pass
Run through (rehearsal): "Let's run through the deck one more time before the client call -- just checking we're all still saying the same numbers."
Walk through (teaching from scratch): "Let me walk you through the deck -- this is your first time seeing the new pricing model."
The first sentence assumes the audience already knows the content and just needs a quick check. The second assumes the audience needs the content explained for the first time, in order.
Offering the wrong one has a real cost
Because the two verbs signal different levels of familiarity, choosing the wrong one either wastes time or leaves a gap.

Insufficient: offering a quick "run through" to a new hire seeing the process for the first time -- they need the sequence explained, not just refreshed.
The rule
Ask whether the listener needs a careful, explanatory first pass, or a quick rehearsal pass over material they already mostly know. Use "walk through" for the first case and "run through" for the second. If the audience is new to the content, "run through" undersells what they actually need; if the audience already knows it well, "walk through" oversells the session and can read as unnecessary or slow.
Practice scenarios
Practice choosing between walk through and run through in situations like:
- offering a quick rehearsal before a presentation the team already knows well
- offering a careful first-time explanation to someone new to the content
- noticing when a scheduled "run through" is actually going to need to be a walkthrough
Useful practice phrases:
- "Let's run through the deck one more time before the client call."
- "Let me walk you through the deck -- this is your first time seeing the new pricing model."
- "This isn't a quick run through -- they've never seen this process before."
Ask how familiar the listener already is. That answer tells you which verb fits.
