yes, there are many ways to cheat, but the way Bruce rides at the moment i have full respect and admiration of his physical and mental ability. he's not using (afaik) tri-bars, which makes riding such distances so much harder - due to aero disadvantage and increased pressure on hands - this is how Tommy did the record too. plus, he currently rides almost self-sufficiently without a support team around. too early to forecast, but i wish him all the best and looking forward to sharing some miles when he's back in the uk.
the above is not to say that i agree with Bruce's decision to do it his own independent way; i'd prefer he's gone through "agency" for the sake of "official" approval.
