Are these times any good for a beginner.

Not a single one of which shows 48km in an hour, equating to 29.8 mph over a full hour. He came close in 2012 but had another 11 minutes to ride at same speed to hit the figure you claimed. An extra 20% over the time he’d already ridden.

So close but no cigar. 😀

There’s one 30 mile (48.203 Km) ride shown, at 1:02.59 which is not under an hour, the 30 milers are all around 55 minutes mark, this is someone who has specifically trained for time trials and is a seriously fast amateur, the majority of TT’s shown are around Cambridgeshire which is notoriously flat, I would also suggest that his times would be a lot worse around the hills of West Yorkshire,

This may be related to the reason why Merckx chose Mexico City over Keighley as the venue for his hour record. Although I hear it was a close run thing.

Merckx should have done it in South Kirkby, he would have gone even faster, he’d have to have done so otherwise someone would have nicked his bike
