A.T. Robertson Commentary Mark 6:33

"And [the people] saw them going, and many knew [them], and they ran together there on foot from all the cities, and outwent them." — Mark 6:33 (ASV)

Outwent them (προηλθον αυτους). The crowds were not to be outdone. They recognized (εγνωσαν) Jesus and the disciples and ran around the head of the lake on foot (πεζη) and got there ahead of Jesus and were waiting for Him when the boat came.
