Hey wanted advice on if we should do anything before our train ride?

Hello we are landing in Madrid in August. Our flight lands at 6:50am Madrid time. If we go through customs / bags maybe a hour or two? Let’s say it’s 9:00. We have a train to catch at chamartin at 11:16 am. We have been told to arrive 30 mins early for the train ride.

Anyway is this gap big enough to go get breakfast somewhere? Or should we just head straight to the train station? I have no clue how long it takes to get from Madrid airport to the train station. My Google Maps says 17 minutes but not sure exactly where we would be leaving from in the airport.
