The event visits Monmouthshire Showground and will start with Primary Challenge races at 12pm. The five race programme then culminates at 2:15pm with the senior / masters and under 20 men’s race.
The relay races see athletes compete over shorter technical courses than would usually be the case and is often able to entice track specialists to compete for their club teams.
Cardiff AAC's women will be looking to defend their title from last year. Lliswerry Runners may be their main competition in the championship contest.
The Cardiff AAC men's team will also start as favourites. Their team will include sub four minute miler Tom Marshall and European Junior 1500m Champion Jake Heyward.
Both senior races are likely to see Cardiff Metroplitan University Teams looking to contend the open race element.
In 2016 titles in the junior races were shared beteen; Cardiff AAC, Carmarthen Harriers, Deeside AAC, Menai Track & Field and Newport Harrirers. All five clubs will be looking to score victiries in 2017.
