My manager loves walking meetings, but I need to write things down

My manager discovered walking meetings this summer and now treats every one-on-one as an opportunity to circle the office park. She says she thinks better while moving. I believe her. I think worse while trying to remember six decisions without a notebook.

The route is pleasant enough: two office buildings, a pond and a loop through the parking lot. For informal conversations it works. The problem is that our one-on-ones are not informal. We discuss project dates, client questions, staffing changes and tasks that need exact owners.

I tried taking notes on my phone while walking. The screen was hard to see outside, typing made me lag behind and I worried that I looked as if I were texting while she spoke. I tried carrying a small notebook, but writing in it while moving produced lines that looked like weather data. When we returned to the office, she immediately joined another meeting and I sat down to reconstruct the conversation from fragments.

Last week I missed one detail about who was contacting a vendor. Nothing serious happened, but the mistake confirmed that the format is costing me accuracy. I asked if we could stop for the final five minutes to capture actions. She said we could “just keep it conversational,” as if the need to document decisions were an unnecessary formality.

I do not want to reject every walking meeting. They are useful when the agenda is brainstorming, feedback or a general check-in. I want the format to match the work. A seated start for decisions followed by a walk for discussion would solve most of it. So would a shared recap sent afterward, but that requires one of us to write it.

How would you raise this without turning a small preference into a wellness-versus-productivity debate? Is it reasonable to ask that any meeting producing assignments includes ten seated minutes?
