Upon being released from service, Becher took a commission as a captain in the Buckinghamshire Yeomanry, but the few demands placed upon him within this role allowed him a great deal of time to pursue his passion of cross-country riding.
It was the last of these races that inspired him to put the idea of a great cross-country chase to racecourse owner and friend William Lynn.
Becher was a regular visitor to Liverpool and Lynn's racecourse at Aintree, famously winning there with the horse with which the public most readily associated him, Vivian.
Fittingly, Becher not only took part but won the race upon a local horse, The Duke, in the lilac and white colours of Mr. Sirdefield.
Becher never again took part in the event but his name was given to the first brook (the sixth and twenty-second fence in the modern National) and has ensured his eternal fame.
