Sir Bradley Wiggins has insisted that he will only make one attempt at breaking the world hour record currently held by Jens Voigt.
The German cyclist set a new fastest time at a velodrome in Switzerland last week, but Wiggins, who will begin training in the winter, is keen to set a new benchmark next year.
The 34-year-old is quoted by BBC Sport as saying: "I want to prepare for it properly. It will give me something to get out of bed for in the winter.
"I was a bit surprised by Jens's decision to do it but what he did was fantastic and fully deserved.
"I could just go and do it next week but if I do it, I'll only do it once."
Chris Boardman was the last British rider to hold the record when he rode 49.441km during the 60-minute time limit.
