JP McManus' record purchase was beaten by stablemate Constitution Hill in the opening race of the 2022 Cheltenham Festival.
Purchased for £570,000 by McManus in November 2020, Jonbon was beaten by 22 lengths as 9/4 favourite Constitution Hill powered up the famous Cheltenham hill.
The turning point of the Grade One was at the third-last flight, when the pace-setting Mullins-trained Dysart Dynamo crashed out, leaving the Henderson pair alone up front.
