What to say instead of “I'm running late”
Why it can fall flat
“I'm running late”
The phrase “I'm running late” makes the delay sound open-ended, so listeners cannot plan around it. Offering a realistic arrival time, respecting their schedule and suggesting a next step gives them something concrete to work with.

Examples
Hi Wesley, I'm running about 15 minutes behind for our 3:00 project review because my earlier meeting is going over. I expect to join by 3:15. If it's easier, we can start with the budget section and I'll pick up the timeline when I arrive. Thanks for your flexibility. Sinead
Quick update: my last meeting is overrunning, so I'll be about 10 minutes behind for the stand-up. I'll join by 9:40 and read the notes straight after.
What to avoid
- Leave no gap where the time should be, because “Be there soon” makes people guess.
- A long backstory adds nothing, and one short reason is enough, or none at all.
- Stacked apologies weaken the message, while one calm update reads as more professional.
- If you're unsure of a time, give a slightly later, realistic one rather than risk a second delay.
- Telling people only after the meeting has started leaves them no chance to adjust.
