"Cesarewitch" is an anglicised version of Tsesarevich, the title of the heir to the throne in Imperial Russia. The race was named in honour of Tsesarevich Alexander (later Tsar Alexander II), after he donated £300 to the Jockey Club. The event was established in 1839, and the inaugural running was won by Cruiskeen. al be buggered, eh...
Today was the first time I'd backed the winner. The only big race I've never had the winner is the 1000 guineas. Come close with Just the Judge and picked out Jacqueline Quest but never had the winner.
