The Wheel World September 1880 gives the results of the Invicta BC club event at Plumstead Sportsman Grounds. The races were a one mile club handicap race and a five miles club handicap. Both races were won by long marker A McQueen. There seems to have been very little bicycle racing at the Sportsman, presumably the nearby Manor Field and Invicta tracks were more popular.
Arsenal FC* played at the Sportsman Ground from 1887 to 1888, but the site suffered from flooding, so they moved the following year to Manor Field which was just a few hundred yards away.
The Sportsman ground was situated where HM Prison Thameside currently stands.
* Arsenal FC were called Royal Arsenal at that time
