The British Speedway Under-21 Championship (also known as the British Junior Speedway Championship) is an annual speedway competition open to riders of British nationality aged at least fifteen on the date of the first meeting, and under twenty-one on 1 January in the year of the competition.
Previous winners include former World Champions Mark Loram and Gary Havelock.
The two riders which accumulate the highest number of points over the heats go straight to the final.
The next four highest point scorers take part in a race-off, with first and second place riders also progressing to the final.
In the final round the reserves may take the rides of any incapacitated rider, replace any rider excluded for a starting infringement, or replace any rider excluded for exceeding the two minute time allowance except in the semi-final or final.
