There were two circuits in Georgetown where the events would take place. The large circuit was 1.95 miles in length with a chicane, two long straights, a back stretch and uphill and downhill turns. This was the battleground of the big machines. The smaller circuit was for the smaller 50cc motorcycles and unmodified Saloon Cars, Classes H, F, G, and E.

During the week prior to the races, the cars were run every day for practice and fine-tuning of the engines and suspension. Several modifications were made to the cars since the circuit was very rough. Initially, all the cars had fenders, but due to the rough track they were eventually all removed.

Many classes were run in Guyana -- from 50 to 750 cc motorcycles, several sedan classes, modified and un-modified sports cars and unrestricted sports cars. The team decision was made to run in the unrestricted sports car class -- the most competitive and fastest cars were in this class.

Team drivers for Guyana consisted of Charlie Moore (who had switched from his Lotus Seven to a U2,) George Beasley in Charlie's ex-Lotus Seven, Mike Tyrell in the other U2 and Jack in his IRS Lotus Seven.

Qualifying began on Saturday, 22 March, 1969 for the two events in which the team was to run. Event # 9 was for the Frederick Mahaica Trophy and Event # 13 was for the Jaguar Trophy. Great qualifying times secured the top three starting positions in a field of fifteen cars.
