CYCLING: Jack Bobridge's next potential cycling hour world record attempt will come after the Rio Olympics and certainly not in the next week.

Scot Graeme Obree, who set the hour record twice during the 1990s, has urged the Australian to back up quickly with another attempt.

Bobridge rode 51.3km on Saturday night in Melbourne, falling short of the 51.852 world mark that Austrian Matthias Brandle set last October.

"That won't be happening," Bobridge's coach Tim Decker told AAP in response to Obree's suggestion.

"I have no doubt that when he goes to do it again, he knows what he's in for.

"It certainly won't be happening in four or five days.

"He can't sit on a bike yet".

Bobridge was a physical mess after the record attempt and said it was the closest he could come to dying.

The 4000m individual pursuit world record holder said it was the hardest thing he had done on a bike.

The first time Obree broke the record in 1993, it was only 24 hours after an unsuccessful attempt at one of cycling's most prestigious marks.

"He should consider trying again, because where he is now is an awful place to be in," Obree told the CyclingTips website.

Bobridge is certain to be named in the Australian team for next month's world track championships and from there he will focus on preparations for the Rio Games.

Immediately after Saturday night's ride, Bobridge said there was no way he would try for the hour record again.

But Decker is confident that one day Bobridge will want another crack.

Decker also defended Bobridge's pacing for the unsuccessful record attempt.

A comparison of pacing charts showed Bobridge started much faster than Brandle and previous world record holder Jens Voigt.

"He couldn't find the right pace," Decker said of his rider.

"But he wasn't just aiming to go 51.9 - the aim was the 52-53km mark.

"He was trying to put a bit of a gap in there.

"He loves trying to put it out there."
