Next year's National Duathlon Championships are set to take place in Yorkshire on 13 April, and will include a free children's race as well as a short "Try a Tri" race.
The event involves a 10km run, followed by a 40km bike and a 5km run, and is likely to be run on closed roads, according to the organisers.
There are also a number of prizes available for all entrants, including a Specialized SHIV and Alias Comp Tri bike.
