IAN Field (Hargroves Cycles) had an unexpected bonus in the gathering gloom at a muddy Peel Park.

Having finished second behind Olympian Liam Killeen in the fifth round of the National Trophy Series in Bradford, the Keighley man was promoted into first place after the former rider was disqualified on a technicality.

Five-times national mountain-bike champion Killeen won by 32 seconds but was thrown out for riding through the pits – his spare bike was not ready for him.

East Morton-based Field, who only needed to finish 21st to ensure that he retained his title but has now won all five of the rounds, admitted: "It's not the way I wanted to win but rules are rules – and it's a UCI race, so I guess that they've got to abide by the rules."

Field, who moved to Keighley two years ago from Ashford in Kent to live with leading women's rider Annabel Simpson, said of his performance: "I didn't know what to expect as I did a training block last week that will see me through for the rest of the season.

"It was super tough out there, but it went okay, and Peel Park is a cracking course – my favourite in the country."

After Killeen's disqualification, Field ended up winning by 1min 7sec, with David Fletcher (Pine Cycles) second and Ian Bibby (NFTO) a further 22 seconds behind in third.

Former Bingley resident Rob Jebb (Hope Factory Racing) had ummed and aahed about riding both the men's 40-49 years' race which opened the programme and the elite men's race which ended it.

In the end, however, the Kendal man decided against riding in both but won the veterans' race anyway, although he was pushed hard by Cononley's Ian Taylor (C and N Cycles).

In order to freshen up the challenge, the course was swapped around, giving the riders two descents instead of one, and Jebb – who won by less than six seconds – said: "The course was difficult, really difficult and really slippery, and anything can happen because you can break your bike at any time."

Taylor, whose brother Andy did not ride because of illness, admitted after the finish: "My hands are really cold and I couldn't change gears."

Haworth's Andy Peace (Jedi Cycle Sport) was eighth.

Shipley's Chris Young (Pedalsport Cycling Club) was third in the men's over-50s race after a sluggish opening.

Series leader Tim Gould (www.Zepnat.com RT) and Grant Johnson (Sunset Cycles) went into the lead and Young said: "It seems like a good idea to make a good start but that's not always the case.

"It is the first time that Grant has beaten me, which will give him confidence ahead of the nationals next month – but the course was really good and cyclo-cross is still the most fun that you can have with your clothes on!"

In the elite women's race, won by two minutes by 18-year-old Evie Richards (T-Mo Racing), Bradford-based Oldfield-Paul Milnes Cycles ERT rider Amira Mellor, from Holmfirth, was fifth, former Otley resident Delia Beddis (Vicious Velo) eighth, Annabel Simpson (Hope Factory Racing) 13th and Mellor's team-mate Sophie Thackray, from Eldwick, 17th.
