The Orton teenager not only broke the record but took it out of sight of any of the area's top triathletes as he blasted round in 47.30.

And it was a performance that even stunned the 17 year-old as he took 92 seconds off Pete Galpin's year-old mark.

Daniels (below) admitted: "I thought I might be able to do 48.30 but I didn't expect to do 47.30, so naturally I'm delighted."

What makes Daniels' time all the more impressive is the fact he had to do it all on his own. Whereas the area's other big names – Matt Gunby, Simon Hoppe and Galpin – are all strong on the bike and run so tend to get better the longer the race goes on, Daniels' best discipline is the swim so he is usually out in front from the start.

Indeed, he was more than a minute clear after the 400 yards swim at Oundle on Wednesday after taking 12 seconds off his previous best split for the discpline.

He then went agonisingly close to Mark Botteley's stage record on the bike, and when you consider Botteley is a former elite racing cyclist that is no mean feat.

Botteley recently broke the record with 22.45 and Daniels was just two seconds slower than that, and amazingly almost two minutes quicker than his best of last year – 24.43.

And his run was also almost two minutes quicker than last year – 20.19 compared to 22.09 in 2007.

That all added up to an improvement of three minutes 58 seconds on his previous best time for the course as he became only the fifth triathlete to break 50 minutes on the course.

No triathlete had ever broken 49 minutes for the course, never mind 48, and it came just four days after he had produced the performance of his life to earn an international call-up.

Daniels was concerned that he might still be feeling tired from his display in a qualifier at Eton that secured his place for the European Youth Championships in Spain in September, but he showed no signs of fatigue.

He added: "I felt really good and just kept pushing on because I wanted to break the record. I wasn't worried about being out in front on my own as I think I'm a pretty good time triallist.

"This year is going so well but I want to get even better. Every time you perform better than you expected you just raise the bar and aim even higher."

Daniels will not tackle the Mini-Series again this year but hopes to take a further minute off his time in 2009. "I'll be disappointed if I don't break 47 minutes next year and maybe I can get down to 46.30 if I go well," he said.

"Long-term I don't know what time I could do on this course. I think the top professionals, people like Tim Don, would probably do 44 minutes but I'll just keep trying to get faster and faster."

As well as being called up for the European Youth Championships in Spain, Daniels – a member of Tri UK as well as PACTRAC – is now in contention to represent his country in Australia in January.

Britain has been invited to send a triathlon team to the Australian Youth Olympic Festival.
