By 1931 three more venues at Beacon Castle,
Devonport and Plymstock Park had all tried the new sport in the Plymouth area. However Pennycross was the only track to survive beyond 1934. Speedway also began at Pennycross in 1931 The general manager of the stadium Freddie Hore signed Australian
Bert Spencer as the first star to ride at Plymouth. Although racing under
National Greyhound Racing Club rules when the track first opened it is believed that the track became independent (unaffiliated to a governing body) sometime before or during the
Second World War. Pennycross Stadium conducted greyhound racing meetings throughout the war under the management of J. Chapman.
Totalisator turnover in 1946 was £1,020,472 during its peak. The stadium had residential housing to its south and as the years passed this increased in size and began to close in around the track on the east and then north. During the sixties the west followed suit resulting in a strange situation where the stadium looked out of place completely surrounded by housing. Pennycross stadium nearly disappeared itself in 1961 after being chosen as the new site for a boys school but it gained a reprieve and an extended lease. In the late 1960s the track continued to race on Wednesday and Saturday nights at 7.30pm, there were two licensed bars and five buffet bars. The track was all-grass with distances of 275, 300, 500, 525, 750 & 800 yards and an inside hare system. == Closure ==
