Age Group National Champs 2015

Hi there, and help appreciated.

The BTF website is an absolute nightmare to use. I'm trying to find the dates for the 2016 Duathlon Age Group National Champs which I think are around March time judging by the 2015 champs (although 2014 champs appeared to be in October?). Surely there is a scheduled event? Does anyone know?

Thanks :0)
