The MGP or Manx (as it is more commonly known) is considered to be the amateur rider's alternative and a learning experience for the Isle of Man TT races held in May/June. The event differs from the TT in that it does not cater for sidecars. A 'Classic TT' race category for historic racing machines was added in 2013 as part of the Manx Government Department of Economic Development's expansion to create what is termed "Festival of Motorcycling". These new races also allowed for professional and experienced riders to compete.
