Usain Bolt says Tyson Gay should have been given a longer ban for drugs cheating, and branded the decision to shorten his punishment 'the stupidest thing I've ever heard'. Gay had his suspension reduced after he agreed to co-operate with authorities, and is now set to compete against Bolt after returning to the sport. But Bolt said he felt 'let down' by the American sprinter, and is not looking forward to competing against a man he used to respect. Usain Bolt says Tyson Gay's reduced ban is 'the stupidest thing I've ever heard' after his doping suspension . Bolt said he used to respect Gay as a competitor, but is no longer looking forward to racing against him . 1. Usain Bolt - Berlin 2009 - 9.58 . 2. Usain Bolt - London 2012 - 9.63 . 3=. Usain Bolt - Beijing 2008 - 9.69 . 3=. Tyson Gay - Berlin 2009 - 9.69 . 3=. Yohan Blake - Lausanne 2012 - 9.69 . 'I was really upset about that,' the world's fastest man said in an interview with Runners World, extracts of which have been published by The Times. 'He got a year just because he talked to the authorities about how it was done and who helped him. 'That sends the wrong message: 'If you do it and get caught, just tell us all you know and we'll lower your ban. 'It's the stupidest thing I've ever heard. The message should be: "If you cheat you're going to be kicked out of the sport."' Bolt stressed that he had regarded Gay, the joint-second fastest man of all time behind the Jamaican, as a rival who kept him on his toes, but now says he will feel no joy competing against the disgraced sprinter. Bolt is the fastest man of all time, but Gay is close behind him and is now returning to the sport . 'It really bothers me,' he added. 'I'm not worried about him beating me, I think it's because I respected him so much over the years. He was a competitor, kept me on my toes and he pushed me to always do my best. 'Then to find out that he was on drugs — it's a bit like I think parents must feel when they have a kid who does something bad and lets them down. I feel like he let me down and he let the sport down.'
