The Manifesto Novices' Chase is a Grade 1 National Huntsteeplechase in Great Britain which is open to horses aged five years or older. It is run at Aintree over a distance of about 2 miles and 4 furlongs (2 miles, 3 furlongs and 200 yards, or 4,005 metres), and during its running there are sixteen fences to be jumped. The race is for novice chasers, and it is scheduled to take place each year during the Grand National meeting in early April.
The event is named after Manifesto, a horse which ran eight times in the Grand National between 1895 and 1904. He won the race twice, finished third on three occasions and was fourth once.
The Manifesto Novices' Chase was established in 2009 as a Grade 2 race, and it features horses which ran previously in the Arkle Challenge Trophy and the JLT Novices' Chase. In 2012 the race was promoted to Grade 1 status.
