George Cartwright (the"Walsall Flyer"),
gets assaulted by a spectator during the
2nd Astley Challenge Belt (1882) held
at the Bingley Hall, Birmingham, England.
It's possible that the attacker had wagered on an opponent of Cartwright during the race as there
was a lot of off-course and track-side betting on
these highly popular events with bookmakers
shouting the odds during races. Contestants were therefore susceptible to attacks whilst competing around the track from disgruntled punters.
