Josiah Charles, 19, Yasir Mohammed, 20, and a 16-year-old boy, who cannot be named for legal reasons, approached the victim at the track in Orton Malborne at about 3pm on 12 May.
Charles, of Medworth, Orton Goldhay, Peterborough, was jailed for three years and Mohammed, of Woodcote Avenue, Barnet, London, was jailed for two years and eight months after being found guilty of attempted robbery at a trial. Both sentences included the activation of six-month suspended sentences.
The boy will be sentenced later this year.
