Anthony Joshua was caught speeding in May and pleaded guilty during his fight week for his clash with Daniel Dubois.
Joshua, 34, pleaded guilty to a speeding charge days before he was knocked out by Daniel Dubois.
He was caught driving at 44mph in a 30mph zone on the A26 in Lewes, East Sussex, on 29 May.
The 2012 Olympic gold medallist was fined £769, ordered to pay £90 costs and a £308 victim surcharge, and given four points on his licence.
In a letter to the court he blamed his training regime and said it may have led to a lapse in concentration.

He wrote: “I am a professional athlete, currently in the middle of a very intense training camp.
“My schedule has been extremely demanding, and I was travelling to or from a training session at the time and date of the offence.
“The physical and mental fatigue from my training may have clouded my judgement, leading to this lapse in concentration.
“I recognise that such circumstances do not justify speeding, and I deeply regret allowing myself to make this error.”
“I would like to respectfully ask the court to consider the potential impact of extra penalty points, which could lead to a driving ban, on my career.
“As an athlete, I rely heavily on my ability to drive to and from training sessions, which are often at locations that are difficult to reach.”
At the weekend the former unified heavyweight champion was beaten by Daniel Dubois in front of over 98,000 fans at a packed Wembley Stadium.
