It depends : vuelta como paseo =stroll vuelta como circuito = lap vuelta puede ser tambien = tour ( vuelta de francia) ,so here most probably so here you would say " i ran 7 strolls or laps "

" i ran 7 strolls or laps " The word "stroll" is used more commonly if you just leisurely walk around the park. "I ran 7 laps" is the most commonly used, for most people use the word 'laps' when your exercising. Stroll doesn't sound proper when you refer to yourself 'running'. Stroll = leisure walk around the park lap = running around the park.
