The riders, some as young as six years of age, were faced with an extremely tough and hilly course, built on the landscaped grassland backdrop of the stadium.
Atherton Godfrey was delighted to show support for the event by sponsoring the Under 8, Under 10 and Under 12 categories.
Charles Godfrey, senior partner said: "What a great way to kick off the school half-term. We are delighted to support this very exciting event.
"There has been renewed interest in cycling as a sport, no doubt helped along by the international successes of The GB Cycling Team."
Thrills and excitement were in full supply as the riders took on the challenge of not only cycling against the clock, but also tackling hills and dismounting to cross obstacles set along the track.
Huge congratulations to all the winners, including Doncaster sisters, Amelia (u10) and Sophie (u8) Morrey, who finished first in their categories. See us on Facebook if you'd like to see photos from the day.
